C | Page 9 of 14TERMINOLOGYRelative AccuracyRelative accuracy or integral nonlinearity (INL) is a measure of the maximum deviation, in least significant bits (LSBs), from an ideal line passing through the endpoints of the DAC transfer function. Figure 4 shows a typical INL vs. code plot. The ADN8810 INL is measured from 2% to 100% of the full-scale (FS) output.Differential NonlinearityDifferential nonlinearity (DNL) is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of ± 1 LSB maximum ensures monotonicity. The ADN8810 is guaranteed monotonic by design. Figure 5 shows a typical DNL vs. code plot . Offset ErrorOffset error, or zero-code error, is an interpolation of the output voltage at code 0x000 as predicted by the line formed from the output voltages at code 0x040 (2% FS) and code 0xFFF (100% FS). Ideally, the offset error is 0 V . Offset error occurs from a combination of the offset voltage of the amplifier and offset errors in the DAC. It is expressed in LSBs.Offset DriftThis is a measure of the change in offset error with a change in temperature. It is expressed in (ppm of full-scale range)/°C. Gain ErrorGain error is a measure of the span error of the DAC. It is the deviation in slope of the output transfer characteristic from ideal. The transfer characteristic is the line formed from the output voltages at code 0x040 (2% FS) and code 0xFFF (100% FS). It is expressed as a percent of the full-scale range.Compliance VoltageThe maximum output voltage from the ADN8810 is a function of output current and supply voltage. Compliance voltage defines the maximum output voltage at a given current and supply voltage to guarantee the device operates within its INL, DNL, and gain error specifications.Output Current Change vs. Output Voltage ChangeThis is a measure of the ADN8810 output impedance and is similar to a load regulation spec in voltage references. For a given code, the output current changes slightly as output voltage increases. It is measured as an absolute value in (ppm of full-scale range)/V .O U T P U T V O L T A G E03195-0-004Figure 16. Output Transfer FunctionADN8810Data SheetRev. C | Page 10 of 14FUNCTIONAL DESCRIPTIONThe ADN8810 is a single 12-bit current output digital-to-analog converter (DAC) with a 3-wire SPI interface. Up to eight devices can be independently programmed from the same SPI bus. The full-scale output current is set with two external resistors. The maximum output current can reach 300 mA. Figure 17 shows the functional block diagram of the ADN8810.03195-0-017Figure 17. Functional Blocks, Pins, and Internal ConnectionsSETTING FULL-SCALE OUTPUT CURRENTTwo external resistors set the full-scale output current from the ADN8810. These resistors are equal in value and are labeled R SN in Figure 1. Use 1% or better tolerance resistors to achieve the most accurate output current and the highest output impedance.Equation 3 shows the approximate full-scale output current. The exact output current is determined by the data register code as shown in Equation 4. The variable code is an integer from 0 to 4095, representing the full 12-bit range of the ADN8810.SNFS R I ×≈10096.4(3)+Ω××=1.0151000,1k R R Code I SN SN OUT(4)The ADN8810 is designed to operate with a 4.096 V referencevoltage connected to VREF. The output current is directly proportional to this reference voltage. To achieve the bestperformance, use a low noise precision (the ADR292, ADR392, or REF198 is recommended).POWER SUPPLIESThere are three principal supply current paths through the ADN8810: •AVDD provides power to the analog front end of the ADN8810 including the DAC. Use this supply line topower the external voltage reference. For best performance, AVDD must be low noise.•DVDD provides power for the digital circuitry. Thisincludes the serial interface logic, the SB and RESET logic inputs, and the FAULT output. Tie DVDD to the same supply line used for other digital circuitry. It is not necessary for DVDD to be low noise.•PVDD is the power pin for the output amplifier. It canoperate from as low as 3.0 V to minimize power dissipation in the ADN8810. For best performance, PVDD must be low noise.Current is returned through the following three pins: •AVSS is the return path for both AVDD and PVDD. This pin is connected to the substrate of the die as well as the slug on the bottom of the lead frame chip scale package (LFCSP). For single-supply operation, connect this pin to a low noise ground plane.•DVSS returns current from the digital circuitry powered by DVDD. Connect DVSS to the same ground line or plane used for other digital devices in the application.•DGND is the ground reference for the digital circuitry. In a single-supply application, connect DGND to DVSS.For single-supply operation, set AVDD to 5 V , set PVDD from 3.0 V to 5 V , and connect AVSS, AGND, and DGND to ground.SERIAL DATA INTERFACEThe ADN8810 uses a serial peripheral interface (SPI) with three input signals: SDI, CLK, and CS . Figure 2 shows the timing diagram for these signals.Data applied to the SDI pin is clocked into the input shift register on the rising edge of CLK. After all 16 bits of the data-word have been clocked into the input shift register, a logic high on CS loads the shift register byte into the ADN8810. If more than 16 bits of data are clocked into the shift register before CS goes high, bits are pushed out of the register in first-in first-out (FIFO) fashion.The four MSB of the data byte are checked against the address of the device. If they match, the next 12 bits of the data byte are loaded into the DAC to set the output current. The first bit (MSB) of the data byte must be a logic zero, and the following three bits must correspond to the logic levels on pins ADDR2, ADDR1, and ADDR0, respectively, for the DAC to be updated. Up to eight ADN8810 devices with unique addresses can be driven from the same serial data bus.Table 5 shows how the 16-bit DATA input word is divided into an address byte and a data byte. The first four bits in the input word correspond to the address. Note that the first bit loaded (A3) must always be zero. The remaining bits set the 12-bit data byte for the DAC output. Three example inputs are demonstrated.•Example 1: This SDI input sets the device with an address of 111 to its minimum output current, 0 A. Connecting the ADN8810 pins ADDR2, ADDR1, and ADDR0 to VDD sets this address.• Example 2: This input sets the device with an address of 000 to a current equal to half of the full-scale output. •Example 3: The ADN8810 with an address of 100 is set to full-scale output.STANDBY AND RESET MODESApplying a logic low to the SB pin deactivates the ADN8810 and puts the output into a high impedance state. The device continues to draw 1.3 mA of typical supply current in standby. When logic high is reasserted on the SB pin, the output current returns to its previous value within 6 µs.Applying logic low to RESET sets the ADN8810 data register to all zeros, bringing the output current to 0 A. When RESET is deasserted, the data register can be reloaded. Data cannot be loaded into the device while it is in standby or reset mode.POWER DISSIPATIONThe power dissipation of the ADN8810 is equal to the output current multiplied by the voltage drop from PVDD to the output.()SN OUT OUT OUT DISS R I V PVDD I P ×−−×=²(5)The power dissipated by the ADN8810 causes a temperature increase in the device. For this reason, PVDD must be as low as possible to minimize power dissipation.While in operation, the ADN8810 die temperature, also known as junction temperature, must remain below 150°C to prevent damage. The junction temperature is approximatelyDISS JA A J P T T ×θ+=(6)where:T A is the ambient temperature in °C,θJA is the thermal resistance of the package (32°C/W). •Example 4: A 300 mA full-scale output current is required to drive a laser diode within an 85°C environment. The laser diode has a 2 V drop and PVDD is 3.3 V .Using Equation 5, the power dissipation in the ADN8810 is found to be 267 mW . At T A = 85°C, this makes the junction temperature 93.5°C, which is well below the 150°C limit. Note that even with PVDD set to 5 V , the junction temperature increases to only 110°C.USING MULTIPLE ADN8810 DEVICES FOR ADDITIONAL OUTPUT CURRENTConnect multiple ADN8810 devices in parallel to increase the available output current. Each device can deliver up to 300 mA of current. To program all parallel devices simultaneously, set all device addresses to the same address byte and drive all CS , SDI, and CLK from the same serial data interface bus. The circuit in Figure 18 uses two ADN8810 devices and delivers 600 mA to the pump laser.SERIAL INTERFACE (FROM µC OR DSP)I 600mA03195-0-018Figure 18.

This is accomplished by dithering the V REF voltage input to the ADN8810. Figure 19 demonstrates one method.DITHERR203195-0-019Figure 19. Adding Dither to the Reference VoltageSet the gain of the dither by adjusting the ratio of R2 to R1. Increase C to lower the cutoff frequency of the high-pass filter created by C and R1. The cutoff frequency of Figure 19 is approximately 98 Hz.The AD8605 is recommended as a low offset, rail-to-rail input amplifier for this circuit.DRIVING COMMON-ANODE LASER DIODESThe ADN8810 can power common-anode laser diodes. These are laser diodes whose anodes are fixed to the laser module case. The module case is typically tied to either VDD or ground. For common anode to ground applications, a −5 V supply must be provided.In Figure 20, R SN sets up the diode current by the following equation:40965.16111.1096.4Code k R I SN ×Ω+×=(7)where Code is an integer value from 0 to 4095.Using the values in Figure 20, the diode current is 300.7 mA at a code value of 2045 (0x7FF), or half full-scale. This effectively provides 11-bit current control from 0 mA to 300 mA of diode current.The maximum output current of this configuration is limited by the compliance voltage at the IOUT pin of the ADN8810. The voltage at IOUT cannot exceed 1 V below PVDD, in this case, 4 V. The IOUT voltage is equal to the voltage drop across R S N plus the gate-to-source voltage of the external FET. For this reason, select a FET with a low threshold voltage.In addition, the voltage across the R SN resistor cannot exceed the voltage at the cathode of the laser diode. Given a forward laser diode voltage drop of 2 V in Figure 20, the voltage at the RSN pin (I × R SN ) cannot exceed 3 V . This sets an upper limit to the value of code in Equation 5.Although the configuration for anode-to-ground diodes is similar, the supply voltages must be shifted down to 0 V and −5 V , as shown in Figure 21. The AVDD, DVDD, and PVDD pins are connected to ground with AVSS connected to −5 V .The 4.096 V reference must also be referred to the −5 V supply voltage. The diode current is still determined by Equation 7. All logic levels must be shifted down to 0 V and −5 V levels as well. This includes RESET , CS , SCLK, SDI, SB , and all ADDR pins. Figure 22 shows a simple method to level shift a standard TTL or CMOS (0 V to 5 V) signal down using external FETs.NOTE: LEAVE FB WITH NO CONNECTION03195-0-020Figure 20.

Level Shifting TTL/CMOS LogicPCB LAYOUT RECOMMENDATIONSAlthough they can be driven from the same power supply voltage, keep DVDD and AVDD current paths separate on the printed circuit board (PCB) to maintain the highest accuracy; likewise for AVSS and DGND. Tie common potentials together at a single point located near the power regulator. This technique is known as star grounding and is shown in Figure 23. This method reduces digital crosstalk into the laser diode or load.LOGIC GROUNDRETURN03195-0-023Figure 23. Star Supply and Ground TechniqueTo improve thermal dissipation, solder the slug on the bottom of the LFCSP package be soldered to the PCB with multiple vias into a low noise ground plane. Connecting these vias to a copper area on the bottom side of the board further improves thermal dissipation.Use identical trace width and lengths for the two output sense resistors. These lengths are shown as X and Y in Figure 24. Differences in trace lengths cause differences in parasitic seriesresistance. Because the sense resistors can be as low as 1.37 Ω, small parasitic differences can lower both the output current accuracy and the output impedance. See the AN-619 Application Note for a sample layout for these traces.03195-0-024Figure 24. Use Identical Trace Lengths for Sense ResistorsSUGGESTED PAD LAYOUT FOR CP-24 PACKAGEFigure 25 shows the dimensions for the PCB pad layout for the ADN8810. The package is a 4 mm × 4 mm, 24-lead LFCSP . The metallic slug underneath the package must be soldered to a copper pad connected to AVSS, the lowest supply voltage to the ADN8810. For single-supply applications, this is ground. Use multiple vias to this pad to improve the thermal dissipation of the package.0.0270.011(0.28)0.020(0.50)CONTROLLING DIMENSIONS ARE IN MILLIMETERS03195-0-025Figure 25.

Rinse and dry thoroughly.ASSEMBLY AND PROPER USE1. Attach the handle (#6) to the gear using the Wing Screw (#5).2. Free the cylinder (#2) for removal by turning/cranking the handle counter-clockwise until the piston isfree of the cylinder. Slide the cylinder out of the frame.3. Place meat in the cylinder. Pack the meat tightly in the cylinder to minimize air pockets.4. Place the cylinder back onto the frame.5. Removing the retaining ring (#3), insert a stuffing tube into the retaining ring. Screw the retaining ringtightly to the unit.6. Slide casings onto stuffing tube.7. Turn the handle clockwise so the piston (#1) moves down into the cylinder and the meat is extrudedthrough the tube and into the casing.8. After extruding all the meat from the cylinder, turn the handle counter-clockwise so the piston backs outof the cylinder.9. Remove the cylinder for cleaning. Wash unit with warm soapy water and thoroughly dry.10. Clean the piston.11. Reassemble and spray with food grade Silicone Spray. (Available at LEM Products.)SALTSalt gives flavor, helps to hold water in the meat, and acts as a binding agent. As a binding agent, salt can cause unnecessary work if instructions are not followed.When salt is mixed with the meat along with other spices and ingredients, it causes the meat to stiffen, or “set-up” very much like cement. This process only requires 20-30 minutes to take affect. It then becomes very difficult to push the meat mixture through the stuffer. With a geared sausage stuffer, a stiffened meat mixture causes unnecessary wear on the gears. We strongly recommend that the meat mixture be packed into the sausage stuffer right after it is mixed. Then, quickly stuff the casings while the meat is pliable. Applying Food Grade Grease to the gears will make the gears work more smoothly and turning the handle much easier.LEM Products recommends that you use 1oz. of water for each pound of meat used. If you are using soy protein concentrate, you can use 2 oz. of water per pound of meat.SOY PROTEINLEM Products recommends the use of our Soy Protein when making sausage. It is available in a 1lb. package, which is enough to mix with 50 lbs. of meat. Use 2 teaspoons of Soy Protein per pound of meat to help retain moisture and prevent shrinking during smoking or cooking. It is very high in protein making it an excellent binder giving the finished sausage a smooth, moist consistency. Soy Protein has no taste, contains no cholesterol and is fat free because it is derived from a vegetable source.Clean the stuffer using a mild detergent and warm water. Rinse and hand dry all parts. With normal use and maintenance, this stuffer will give you years of enjoyment. After washing the unit, spray it with a food grade Silicone Spray. This will prevent oxidation and will keep your stuffer like new. This silicone coating can be washed off easily with hot soapy water before the next use. Silicone Spray is available from LEM Products.。

OP Code: Operand Code. A0~A11 & BA0~BA1 : Program keys. (@EMRS/MRS)2. EMRS/MRS can be issued only at all banks precharge state.A new command can be issued 1 clock cycles after EMRS or MRS.3. Auto refresh functions are same as the CBR refresh of DRAM.The automatical precharge without row precharge command is meant by “Auto”..Auto/self refresh can be issued only at all banks precharge state.4. BA0~BA1 : Bank select addresses.If both BA0 and BA1 are “Low” at read, write, row active and precharge, bank A is selected.If BA0 is “High” and BA1 is “Low” at read, write, row active and precharge, bank B is selected.If BA0 is “Low” and BA1 is “High” at read, write, row active and precharge, bank C is selected.If both BA0 and BA1 are “High” at read, write, row active and precharge, bank D is selected.5. If A10/AP is “High” at row precharge, BA0 and BA1 are ignored and all banks are selected.6. During burst write with auto precharge, new read/write command can not be issued.Another bank read/write command can be issued after the end of burst.New row active of the associated bank can be issued at t RP after end of burst.7. Burst stop command is valid at every burst length.8. DM sampling at the rising and falling edges of the DQS and Data-in are masked at the both edges (Write DM latency is 0).Basic FunctionalityPower-Up and Initialization SequenceThe following sequence is required for POWER UP and Initialization.1. Apply power and attempt to maintain CKE at a low state (all other inputs may be undefined.)-Apply VDD before or at the same time as VDDQ.-Apply VDDQ before or at the same time as V TT & V REF).2. Start clock and maintain stable condition for a minimun of 200us.3. The minimun of 200us after stable power and clock (CLK, CLK), apply NOP & take CKE high.4. Issue precharge commands for all banks of the device.*1 5. I ssue EMRS to enable DLL. (To issue “DLL Enable” command, provide “Low” to A0, “High” to BA0 and “Low” to all of the rest address pins, A1~A11 and BA1)*1 6. Issue a mode register set command for “DLL reset”. The additional 200 cycles of clock input is required to lock the DLL.(To issue DLL reset command, provide “High” to A8 and “Low” to BA0)*2 7. Issue precharge commands for all banks of the device.8. Issue 2 or more auto-refresh commands.9. Issue a mode register set command with low to A8 to initialize device operation.*1 Every “DLL enable” command resets DLL. Therefore sequence 6 can be skipped during power up. Instead of it, the additional 200 cycles of clock input is required to lock the DLL after enabling DLL.*2 Sequence of 6 & 7 is regardless of the order.Mode Register DefinitionMode Register Set (MRS)The mode register stores the data for controlling the various operating modes of DDR SDRAM. It programs CAS latency, addressing mode, burst length, test mode, DLL reset and various vendor specific options to make DDR SDRAM useful for variety of different applications. The default value of the register is not defined, therefore the mode register must be written after EMRS setting for proper DDR SDRAM operation. The mode register is written by asserting low on CS, RAS, CAS, WE and BA0 (The DDR SDRAM should be in all bank precharge with CKE already high prior to writing into the mode register). The state of address pins A0~A11 in the same cycle as CS, RAS, CAS, WE and BA0 going low is written in the mode register. Two clock cycles are requested to complete the write operation in the mode register. The mode register contents can be changed using the same command and clock cycle requirements during operation as long as all banks are in the idle state. The mode register is divided into various fields depending on functionality. The burst length uses A0~A2, addressing mode uses A3, CAS latency (read latency from column address) uses A4~A6. A7 is used for test mode. A8 is used for DLL reset. A7 must be set to low for normal MRS operation. Refer to the table for specific codes for various burst length, addressing modes and CAS latencies.Bus BA1 BA0 A11 A10A9 A8 A7A6A5A4A3A2A1 A0 AddressBurst Address Ordering for Burst LengthBurst Length StartingAddress (A2, A1,A0)Sequential Mode Interleave Mode xx0 0, 1 0, 1 2xx1 1, 0 1, 0 x00 0, 1, 2, 3 0, 1, 2, 3 x01 1, 2, 3, 0 1, 0, 3, 2 x10 2, 3, 0, 1 2, 3, 0, 1 4x11 3, 0, 1, 23, 2, 1, 0000 0, 1, 2, 3, 4, 5, 6, 7 0, 1, 2, 3, 4, 5, 6, 7 001 1, 2, 3, 4, 5, 6, 7, 0 1, 0, 3, 2, 5, 4, 7, 6 010 2, 3, 4, 5, 6, 7, 0, 1 2, 3, 0, 1, 6, 7, 4, 5 011 3, 4, 5, 6, 7, 0, 1, 2 3, 2, 1, 0, 7, 6, 5, 4 100 4, 5, 6, 7, 0, 1, 2, 3 4, 5, 6, 7, 0, 1, 2, 3 101 5, 6, 7, 0, 1, 2, 3, 4 5, 4, 7, 6, 1, 0, 3, 2 110 6, 7, 0, 1, 2, 3, 4, 5 6, 7, 4, 5, 2, 3, 0, 1 81117, 0, 1, 2, 3, 4, 5, 67, 6, 5, 4, 3, 2, 1, 0DLL Enable / DisableThe DLL must be enabled for normal operation. DLL enable is required during power-up initialization, and upon returning to normal operation after having disabled the DLL for the purpose of debug or evaluation (upon exiting Self Refresh Mode, the DLL is enable automatically). Any time the DLL is enabled, 200 clock cycles must occur before a READ command can be issued.Output Drive StrengthThe normal drive strength for all outputs is specified to be SSTL_2, Class II. M13S128168A also support a weak drive strength option, intended for lighter load and/or point-to-point environments.Mode Register SetExtended Mode Register Set (EMRS)The extended mode register stores the data enabling or disabling DLL. The default value of the extended mode register is not defined, therefore the extended mode register must be written after power up for enabling or disabling DLL. The extended mode register is written by asserting low on CS, RAS, CAS, WE and high on BA0 (The DDR SDRAM should be in all bank precharge with CKE already high prior to writing into the extended mode register). The state of address pins A0~A11 and BA1 in the same cycle as CS, RAS, CAS and WE going low is written in the extended mode register. The mode register contents can be changed using the same command and clock cycle requirements during operation as long as all banks are in the idle state. A0 is used for DLL enable or disable. “High” on BA0 is used for EMRS. All the other address pins except A0 and BA0 must be set to low for proper EMRS operation. Refer to the table for specific codes.*QFC is not used; don’t care.PrechargeThe precharge command is used to precharge or close a bank that has activated. The precharge command is issued when CS, RAS and WE are low and CAS is high at the rising edge of the clock. The precharge command can be used to precharge each bank respectively or all banks simultaneously. The bank select addresses (BA0, BA1) are used to define which bank is precharged when the command is initiated. For write cycle, t WR(min.) must be satisfied until the precharge command can be issued. After t RP from the precharge, an active command to the same bank can be initiated.Burst Selection for Precharge by Bank address bitsA10/AP BA1 BA0 PrechargeOnlyABank0 0 0BOnlyBank0 0 1COnlyBank0 1 0OnlyDBank0 1 1AllBanks1 X XNOP & Device DeselectThe device should be deselected by deactivating the CS signal. In this mode DDR SDRAM should ignore all the control inputs. The DDR SDRAMs are put in NOP mode when CS is active and by deactivating RAS, CAS and WE. For both Deselect and NOP the device should finish the current operation when this command is issued.Row ActiveThe Bank Activation command is issued by holding CAS and WE high with CS and RAS low at the rising edge of the clock (CLK). The DDR SDRAM has four independent banks, so two Bank Select addresses (BA0, BA1) are required. The Bank Activation command to the first read or write command must meet or exceed the minimum of RAS to CAS delay time (t RCD min). Once a bank has been activated, it must be precharged before another Bank Activation command can be applied to the same bank. The minimum time interval between interleaved Bank Activation command (Bank A to Bank B and vice versa) is the Bank to Bank delay time (t RRD min).Read BankThis command is used after the row activate command to initiate the burst read of data. The read command is initiated by activating CS, CAS, and deasserting WE at the same clock sampling (rising) edge as described in the command truth table. The length of the burst and the CAS latency time will be determined by the values programmed during the MRS command.Write BankThis command is used after the row activate command to initiate the burst write of data. The write command is initiated by activating CS, CAS, and WE at the same clock sampling (rising) edge as describe in the command truth table. The length of the burst will be determined by the values programmed during the MRS command.Essential Functionality for DDR SDRAMBurst Read OperationBurst Read operation in DDR SDRAM is in the same manner as the current SDRAM such that the Burst read command is issued by asserting CS and CAS low while holding RAS and WE high at the rising edge of the clock (CLK) after t RCD from the bank activation. The address inputs determine the starting address for the Burst, The Mode Register sets type of burst (Sequential or interleave) and burst length (2, 4, 8). The first output data is available after the CAS Latency from the READ command, and the consecutive data are presented on the falling and rising edge of Data Strobe (DQS) adopted by DDR SDRAM until the burst length is completed.Burst Write OperationThe Burst Write command is issued by having CS, CAS and WE low while holding RAS high at the rising edge of the clock (CLK). The address inputs determine the starting column address. There is no write latency relative to DQS required for burst write cycle. The first data of a burst write cycle must be applied on the DQ pins t DS (Data-in setup time) prior to data strobe edge enabled after t DQSS from the rising edge of the clock (CLK) that the write command is issued. The remaining data inputs must be supplied on each subsequent falling and rising edge of Data Strobe until the burst length is completed. When the burst has been finished, any additional data supplied to the DQ pins will be ignored.Read Interrupted by a ReadA Burst Read can be interrupted before completion of the burst by new Read command of any bank. When the previous burst is interrupted, the remaining addresses are overridden by the new address with the full burst length. The data from the first Read command continues to appear on the outputs until the CAS latency from the interrupting Read command is satisfied. At this point the data from the interrupting Read command appears. Read to Read interval is minimum 1 Clock.Read Interrupted by a PrechargeA Burst Read operation can be interrupted by precharge of the same bank. The minimum 1 clock is required for the read to precharge intervals. A precharge command to output disable latency is equivalent to the CAS latency.When a burst Read command is issued to a DDR SDRAM, a Precharge command may be issued to the same bank before the Read burst is complete. The following functionality determines when a Precharge command may be given during a Read burst and when a new Bank Activate command may be issued to the same bank.1. For the earliest possible Precharge command without interrupting a Read burst, the Precharge command may be given on therising clock edge which is CL clock cycles before the end of the Read burst where CL is the CAS Latency. A new Bank Activate command may be issued to the same bank after t RP (RAS precharge time).2. When a Precharge command interrupts a Read burst operation, the Precharge command may be given on the rising clock edgewhich is CL clock cycles before the last data from the interrupted Read burst where CL is the CAS Latency. Once the last data word has been output, the output buffers are tristated. A new Bank Activate command may be issued to the same bank after t RP.3. For a Read with autoprecharge command, a new Bank Activate command may be issued to the same bank after t RP where t RPbegins on the rising clock edge which is CL clock cycles before the end of the Read burst where CL is the CAS Latency.During Read with autoprecharge, the initiation of the internal precharge occurs at the same time as the earliest possible external Precharge command would initiate a precharge operation without interrupting the Read burst as described in 1 above.4. For all cases above, t RP is an analog delay that needs to be converted into clock cycles. The number of clock cycles between aPrecharge command and a new Bank Activate command to the same bank equals t RP / t CK (where t CK is the clock cycle time) with the result rounded up to the nearest integer number of clock cycles.In all cases, a Precharge operation cannot be initiated unless t RAS(min) [minimum Bank Activate to Precharge time] has been satisfied. This includes Read with autoprecharge commands where t RAS(min) must still be satisfied such that a Read with autoprecharge command has the same timing as a Read command followed by the earliest possible Precharge command which does not interrupt the burst.Write Interrupted by a WriteA Burst Write can be interrupted before completion of the burst by a new Write command, with the only restriction that the interval that separates the commands must be at least one clock cycle. When the previous burst is interrupted, the remaining addresses are overridden by the new address and data will be written into the device until the programmed burst length is satisfied.The following functionality establishes how a Write command may interrupt a Read burst.1. For Write commands interrupting a Read burst, a Read burst, a Burst Terminate command is required to stop the read burstand tristate the DQ bus prior to valid input write data. Once the Burst Terminate command has been issued, the minimum delay to a Write command = RU(CL) [CL is the CAS Latency and RU means round up to the nearest integer].2. It is illegal for a Write command to interrupt a Read with autoprecharge command.Write Interrupted by a Read & DMA burst write can be interrupted by a read command of any bank. The DQ’s must be in the high impedance state at least one clock cycle before the interrupting read data appear on the outputs to avoid data contention. When the read command is registered, any residual data from the burst write cycle must be masked by DM. The delay from the last data to read command (t WTR) is required to avoid the data contention DRAM inside. Data that are presented on the DQ pins before the read command is initiated will actually be written to the memory. Read command interrupting write can not be issued at the next clock edge of that of write command.The following functionality established how a Read command may interrupt a Write burst and which input data is not written into the memory.1. For Read commands interrupting a Write burst, the minimum Write to Read command delay is 2 clock cycles. The case wherethe Write to Read delay is 1 clock cycle is disallowed.2. For read commands interrupting a Write burst, the DM pin must be used to mask the input data words which immediatelyprecede the interrupting Read operation and the input data word which immediately follows the interrupting Read operation.3. For all cases of a Read interrupting a Write, the DQ and DQS buses must be released by the driving chip (i.e., the memorycontroller) in time to allow the buses to turn around before the SDRAM drives them during a read operation.4. If input Write data is masked by the Read command, the DQS inputs is ignored by the SDRAM.5. It is illegal for a Read command interrupt a Write with autoprecharge command.Write Interrupted by a Precharge & DMA burst write operation can be interrupted before completion of the burst by a precharge of the same bank. Random column access is allowed. A write recovery time (t WR) is required from the last data to precharge command. When precharge command is asserted, any residual data from the burst write cycle must be masked by DM.Precharge timing for Write operations in DRAMs requires enough time to allow “Write recovery” which is the time required by a DRAM core to properly store a full “0” or “1” level before a Precharge operation. For DDR SDRAM, a timing parameter, t WR, is used to indicate the required of time between the last valid write operation and a Precharge command to the same bank.The precharge timing for writes is a complex definition since the write data is sampled by the data strobe and the address is sampled by the input clock. Inside the SDRAM, the data path is eventually synchronizes with the address path by switching clock domains from the data strobe clock domain to the input clock domain.This makes the definition of when a precharge operation can be initiated after a write very complex since the write recovery parameter must reference only the clock domain that is used to time the internal write operation i.e., the input clock domain.t WR starts on the rising clock edge after the last possible DQS edge that strobed in the last valid and ends on the rising clock edge that strobes in the precharge command.1. For the earliest possible Precharge command following a Write burst without interrupting the burst, the minimum time for writerecovery is defined by t WR.2. When a precharge command interrupts a Write burst operation, the data mask pin, DQ, is used to mask input data during thetime between the last valid write data and the rising clock edge in which the Precharge command is given. During this time, the DQS input is still required to strobe in the state of DM.The minimum time for write recovery is defined by t WR.3. For a Write with autoprecharge command, a new Bank Activate command may be issued to the same bank after t WR + t RP wheret WR + t RP starts on the falling DQS edge that strobed in the last valid data and ends on the rising clock edge that strobes in the Bank Activate commands. During write with autoprecharge, the initiation of the internal precharge occurs at the same time as the earliest possible external Precharge command without interrupting the Write burst as described in 1 above.4. In all cases, a Precharge operation cannot be initiated unless t RAS(min) [minimum Bank Activate to Precharge time] has beensatisfied. This includes Write with autoprecharge commands where t RAS(min) must still be satisfied such that a Write with autoprecharge command has the same timing as a Write command followed by the earliest possible Precharge command which does not interrupt the burst.Burst StopThe burst stop command is initiated by having RAS and CAS high with CS and WE low at the rising edge of the clock (CLK). The burst stop command has the fewest restriction making it the easiest method to use when terminating a burst read operation before it has been completed. When the burst stop command is issued during a burst read cycle, the pair of data and DQS (Data Strobe) go to a high impedance state after a delay which is equal to the CAS latency set in the mode register. The burst stop command, however, is not supported during a write burst operation.The Burst Stop command is a mandatory feature for DDR SDRAMs. The following functionality is required.1. The BST command may only be issued on the rising edge of the input clock, CLK.2. BST is only a valid command during Read burst.3. BST during a Write burst is undefined and shall not be used.4. BST applies to all burst lengths.5. BST is an undefined command during Read with autoprecharge and shall not be used.6. When terminating a burst Read command, the BST command must be issued L BST ( “BST Latency”) clock cycles before theclock edge at which the output buffers are tristated, where L BST equals the CAS latency for read operations.7. When the burst terminates, the DQ and DQS pins are tristated.The BST command is not byte controllable and applies to all bits in the DQ data word and the (all) DQS pin(s).DM maskingThe DDR SDRAM has a data mask function that can be used in conjunction with data write cycle. Not read cycle. When the data mask is activated (DM high) during write operation, DDR SDRAM does not accept the corresponding data. (DM to data-mask latency is zero) DM must be issued at the rising or falling edge of data strobe.Read With Auto PrechargeIf a read with auto-precharge command is initiated, the DDR SDRAM automatically enters the precharge operation BL/2 clock later from a read with auto-precharge command when t RAS(min) is satisfied. If not, the start point of precharge operation will be delayed until t RAS(min) is satisfied. Once the precharge operation has started the bank cannot be reactivated and the new command can not be asserted until the precharge time (t RP) has been satisfiedAt burst read / write with auto precharge, CAS interrupt of the same bank is illegal.。

The * marking branded on the component designates DIN VDE V 0884-11 approval.4.0 FUNCTION DESCRIPTIONThe NSi812x is a Dual-channel digital isolator based on a capacitive isolation barrier technique. The digital signal is modulated with RF carrier generated by the internal oscillator at the Transmitter side. Then it is transferred through the capacitive isolation barrier and demodulated at the Receiver side.The NSi812x devices are high reliability dual-channel digital isolator with AEC-Q100 qualified. The NSi812x device is safety certified by UL1577 support several insulation withstand voltages (3.75kV rms , 5kV rms ), while providing high electromagnetic immunity and low emissions at low power consumption. The data rate of the NSi812x is up to 150Mbps, and the common-mode transient immunity (CMTI) is up to 150kV/us. The NSi812x device provides digital channel direction configuration and the default output level configuration when the input power is lost. Wide supply voltage of the NSi812x device support to connect with most digital interface directly, easy to do the level shift. High system level EMC performance enhance reliability and stability of use.The NSi812x has a default output status when VDDIN is unready and VDDOUT is ready as shown in Table 4.1, which helps for diagnosis when power is missing at the transmitter side. The output B follows the same status with the input A within 1us after powering up.C O NF ID EN T IA LCopyright © 2019, NOVOSENSEPage 12 Table 4.1 Output status vs. power statusH Ready Ready H Normal operation.L Ready Ready L XUnreadyReadyL HThe output follows the same status with the input within 60us after input side VDD1 is powered on.X Ready Unready XThe output follows the same status with the input within 60us after output side VDD2 is powered on.5.0 APPLICATION NOTE5.1. PCB LAYOUTThe NSi812x requires a 0.1 µF bypass capacitor between VDD1 and GND1, VDD2 and GND2. The capacitor should beplaced as close as possible to the package. Figure 5.1 to Figure 5.4 show the recommended PCB layout, make sure the space under the chip should keep free from planes, traces, pads and via. To enhance the robustness of a design, the user may also include resistors (50–300 Ω ) in series with the inputs and outputs if the system is excessively noisy. The series resistors also improve the system reliability such as latch-up immunity.The typical output impedance of an isolator driver channel is approximately 50 Ω, ±40%. When driving loads where transmission line effects will be a factor, output pins should be appropriately terminated with controlled impedance PCB traces.Figure5.1 Recommended PCB Layout — Top Layer Figure5.2 Recommended PCB Layout — Bottom LayerFigure5.3 Recommended PCB Layout — Top Layer Figure5.4 Recommended PCB Layout — Bottom Layer5.2.

All operations are synchronized to the positive going edge of the clock. The clock transitions must be monotonic between V IL and V IH. During operation with CKE high all inputs are assumed to be in valid state (low or high) for the duration of setup and hold time around positive edge of the clock for proper functionality and I CC specifications.CLOCK ENABLE(CKE)The clock enable (CKE) gates the clock onto SDRAM. If CKE goes low synchronously with clock (set-up and hold time same as other inputs), the internal clock suspended from the next clock cycle and the state of output and burst address is frozen as long as the CKE remains low. All other inputs are ignored from the next clock cycle after CKE goes low. When all banks are in the idle state and CKE goes low synchronously with clock, the SDRAM enters the power down mode from the next clock cycle. The SDRAM remains in the power down mode ignoring the other inputs as long as CKE remains low. The power down exit is synchronous as the internal clock is suspended. When CKE goes high at least “1CLK + t SS” before the high going edge of the clock, then the SDRAM becomes active from the same clock edge accepting all the input commands.BANK ADDRESSES (BA0~BA1)This SDRAM is organized as four independent banks of 2,097,152 words x 16 bits memory arrays. The BA0~BA1 inputs are latched at the time of assertion of RAS and CAS to select the bank to be used for the operation. The banks addressed BA0~BA1 are latched at bank active, read, write, mode register set and precharge operations.ADDRESS INPUTS (A0~A11)The 21 address bits are required to decode the 2,097,152 word locations are multiplexed into 12 address input pins (A0~A11). The 12 row addresses are latched along with RAS and BA0~BA1 during bank active command. The 9 bit column addresses are latched along with CAS, WE and BA0~BA1 during read or with command.NOP and DEVICE DESELECTWhen RAS, CAS and WE are high , The SDRAM performs no operation (NOP). NOP does not initiate any new operation, but is needed to complete operations which require more than single clock cycle like bank activate, burst read, auto refresh, etc. The device deselect is also a NOP and is entered by asserting CS high. CS high disables the command decoder so that RAS, CAS, WE and all the address inputs are ignored. POWER-UP1.Apply power and start clock, Attempt to maintain CKE = “H”, DQM = “H” and the other pins are NOP condition at the inputs.2.Maintain stable power, stable clock and NOP input condition for minimum of 200us.3.Issue precharge commands for all banks of the devices.4.Issue 2 or more auto-refresh commands.5.Issue a mode register set command to initialize the mode register.cf.) Sequence of 4 & 5 is regardless of the order.The device is now ready for normal operation.MODE REGISTER SET (MRS)The mode register stores the data for controlling the various operating modes of SDRAM. It programs the CAS latency, burst type, burst length, test mode and various vendor specific options to make SDRAM useful for variety of different applications. The default value of the mode register is not defined, therefore the mode register must be written after power up to operate the SDRAM. The mode register is written by asserting low on CS, RAS, CAS and WE(The SDRAM should be in active mode with CKE already high prior to writing the mode register). The state of address pins A0~A11 and BA0~BA1in the same cycle as CS, RAS, CAS and WE going low is the data written in the mode register. Two clock cycles is required to complete the write in the mode register. The mode register contents can be changed using the same command and clock cycle requirements during operation as long as all banks are in the idle state. The mode register is divided into various fields into depending on functionality. The burst length field uses A0~A2, burst type uses A3, CAS latency (read latency from column address) use A4~A6, vendor specific options or test mode use A7~A8, A10/AP~A11 and BA0~BA1. The write burst length is programmed using A9. A7~A8, A10/AP~A11 and BA0~BA1 must be set to low for normal SDRAM operation. Refer to the table for specific codes for various burst length, burst type and CAS latencies.BANK ACTIVATEThe bank activate command is used to select a random row in an idle bank. By asserting low on RAS and CS with desired row and bank address, a row access is initiated. The read or write operation can occur after a time delay of t RCD(min) from the time of bank activation. t RCD is the internal timing parameter of SDRAM, therefore it is dependent on operating clock frequency. The minimum number of clock cycles required between bank activate and read or write command should be calculated by dividing t RCD(min) with cycle time of the clock and thenElite Semiconductor Memory Technology Inc.Publication Date: Jul. 2010DEVICE OPERATIONS (Continued)rounding of the result to the next higher integer. The SDRAM has four internal banks in the same chip and shares part of the internal circuitry to reduce chip area, therefore it restricts the activation of four banks simultaneously. Also the noise generated during sensing of each bank of SDRAM is high requiring some time for power supplies to recover before another bank can be sensed reliably. t RRD(min) specifies the minimum time required between activating different bank. The number of clock cycles required between different bank activation must be calculated similar to t RCD specification. The minimum time required for the bank to be active to initiate sensing and restoring the complete row of dynamic cells is determined by t RAS(min). Every SDRAM bank activate command must satisfy t RAS(min) specification before a precharge command to that active bank can be asserted. The maximum time any bank can be in the active state is determined by t RAS(max) and t RAS(max) can be calculated similar to t RCD specification.BURST READThe burst read command is used to access burst of data on consecutive clock cycles from an active row in an active bank. The burst read command is issued by asserting low on CSand RAS with WE being high on the positive edge of the clock. The bank must be active for at least t RCD(min)before the burst read command is issued. The first output appears in CAS latency number of clock cycles after the issue of burst read command. The burst length, burst sequence and latency from the burst read command is determined by the mode register which is already programmed. The burst read can be initiated on any column address of the active row. The address wraps around if the initial address does not start from a boundary such that number of outputs from each I/O are equal to the burst length programmed in the mode register. The output goes into high-impedance at the end of burst, unless a new burst read was initiated to keep the data output gapless. The burst read can be terminated by issuing another burst read or burst write in the same bank or the other active bank or a precharge command to the same bank. The burst stop command is valid at every page burst length.BURST WRITEThe burst write command is similar to burst read command and is used to write data into the SDRAM on consecutive clock cycles in adjacent addresses depending on burst length and burst sequence. By asserting low on CS, CAS and WE with valid column address, a write burst is initiated. The data inputs are provided for the initial address in the same clock cycle as the burst write command. The input buffer is deselected at the end of the burst length, even though the internal writing can be completed yet. The writing can be complete by issuing a burst read and DQM for blocking data inputs or burst write in the same or another active bank. The burst stop command is valid at every burst length. The write burst can also be terminated by using DQM for blocking data and precharge the bank t RDL after the last data input to be written into the active row. See DQM OPERATION also. DQM OPERATIONThe DQM is used mask input and output operations. It works similar to OE during operation and inhibits writing during write operation. The read latency is two cycles from DQM and zero cycle for write, which means DQM masking occurs two cycles later in read cycle and occurs in the same cycle during write cycle. DQM operation is synchronous with the clock. The DQM signal is important during burst interrupts of write with read or precharge in the SDRAM. Due to asynchronous nature of the internal write, the DQM operation is critical to avoid unwanted or incomplete writes when the complete burst write is required. Please refer to DQM timing diagram also. PRECHARGEThe precharge is performed on an active bank by asserting low on clock cycles required between bank activate and clock cycles required between bank activate and CS, RAS, WE and A10/AP with valid BA0~BA1 of the bank to be procharged. The precharge command can be asserted anytime after t RAS(min) is satisfy from the bank active command in the desired bank. t RP is defined as the minimum number of clock cycles required to complete row precharge is calculated by dividing t RP with clock cycle time and rounding up to the next higher integer. Care should be taken to make sure that burst write is completed or DQM is used to inhibit writing before precharge command is asserted. The maximum time any bank can be active is specified by t RAS(max). Therefore, each bank has to be precharge with t RAS(max) from the bank activate command. At the end of precharge, the bank enters the idle state and is ready to be activated again. Entry to power-down, Auto refresh, Self refresh and Mode register set etc. is possible only when all banks are in idle state.AUTO PRECHARGEThe precharge operation can also be performed by using auto precharge. The SDRAM internally generates the timing to satisfy t RAS(min) and “t RP” for the programmed burst length and CAS latency. The auto precharge command is issued at the same time as burst write by asserting high on A10/AP, the bank is precharge command is asserted. Once auto precharge command is given, no new commands are possible to that particular bank until the bank achieves idle state.FOUR BANKS PRECHARGEFour banks can be precharged at the same time by using Precharge all command. Asserting low on CS, RAS, and WE with high on A10/AP after all banks have satisfied t RAS(min)requirement, performs precharge on all banks. At the end of t RP after performing precharge all, all banks are in idle state.Elite Semiconductor Memory Technology Inc.Publication Date: Jul. 2010DEVICE OPERATIONS (Continued)AUTO REFRESHThe storage cells of SDRAM need to be refreshed every 64ms to maintain data. An auto refresh cycle accomplishes refresh of a single row of storage cells. The internal counter increments automatically on every auto refresh cycle to refresh all the rows. An auto refresh command is issued by asserting low on CS, RAS and CAS with high on CKE and WE. The auto refresh command can only be asserted with all banks being in idle state and the device is not in power down mode (CKE is high in the previous cycle). The time required to complete the auto refresh operation is specified by t RFC(min). The minimum number of clock cycles required can be calculated by driving t RFC with clock cycle time and them rounding up to the next higher integer. The auto refresh command must be followed by NOP’s until the auto refresh operation is completed. The auto refresh is the preferred refresh mode when the SDRAM is being used for normal data transactions. The auto refresh cycle can be performed once in 15.6us. SELF REFRESHThe self refresh is another refresh mode available in the SDRAM. The self refresh is the preferred refresh mode for data retention and low power operation of SDRAM. In self refresh mode, the SDRAM disables the internal clock and all the input buffers except CKE. The refresh addressing and timing is internally generated to reduce power consumption.The self refresh mode is entered from all banks idle state by asserting low on CS, RAS, CAS and CKE with high on WE. Once the self refresh mode is entered, only CKE state being low matters, all the other inputs including clock are ignored to remain in the refresh.The self refresh is exited by restarting the external clock and then asserting high on CKE. This must be followed by NOP’s for a minimum time of t RFC before the SDRAM reaches idle state to begin normal operation. 4K cycles of burst auto refresh is required immediately before self refresh entry and immediately after self refresh exit.Elite Semiconductor Memory Technology Inc.Publication Date: Jul. 2010Mode register set command(CS,RAS,CAS,WE =Low)The M12L128168A has a mode register that defines how the device operates. Inthis command, A0~A11 and BA0~BA1 are the data input pins. After power on, themode register set command must be executed to initialize the device.The mode register can be set only when all banks are in idle state.During 2CLK following this command, the M12L128168A cannot accept anyother commands.(CS,RAS =Low,CAS,WE= High)The M12L128168A has four banks, each with 4,096 rows.This command activates the bank selected by BA1 and BA0 (BS) and a rowaddress selected by A0 through A11.This command corresponds to a conventional DRAM’s RAS falling.Precharge command(CS,RAS,WE =Low,CAS= High )This command begins precharge operation of the bank selected by BA1 and BA0(BS). When A10 is High, all banks are precharged, regardless of BA1 and BA0.When A10 is Low, only the bank selected by BA1 and BA0 is precharged.After this command, the M12L128168A can’t accept the activate command to theprecharging bank during t RP (precharge to activate command period).This command corresponds to a conventional DRAM’s RAS rising.Elite Semiconductor Memory Technology Inc.Publication Date: Jul. 2010Elite Semiconductor Memory Technology Inc. Publication Date : Jul. 2010Write command(CS ,CAS ,WE = Low, RAS = High)If the mode register is in the burst write mode, this command sets the burst start address given by the column address to begin the burst write operation. The first write data in burst can be input with this command with subsequent data on following clocks.Read command(CS ,CAS = Low, RAS ,WE = High)Read data is available after CAS latency requirements have been met. This command sets the burst start address given by the column address.CBR (auto) refresh command(CS ,RAS ,CAS = Low, WE , CKE = High)This command is a request to begin the CBR refresh operation. The refresh address is generated internally.Before executing CBR refresh, all banks must be precharged.After this cycle, all banks will be in the idle (precharged) state and ready for arow activate command.During t RFCperiod (from refresh command to refresh or activate command), the M12L128168A cannot accept any other command.Self refresh entry command(CS,RAS,CAS, CKE = Low ,WE =High)After the command execution, self refresh operation continues while CKE remains low. When CKE goes to high, the M12L128168A exits the self refresh mode.During self refresh mode, refresh interval and refresh operation are performed internally, so there is no need for external control.Before executing self refresh, all banks must be precharged.Burst stop command(CS,WE =Low,RAS,CAS =High)This command terminates the current burst operation.Burst stop is valid at every burst length.No operation(CS= Low ,RAS,CAS,WE=High)This command is not a execution command. No operations begin or terminate bythis command.Elite Semiconductor Memory Technology Inc.Publication Date: Jul. 2010BASIC FEATURE AND FUNCTION DESCRIPTIONS1. CLOCK Suspend*Note: 1.

maxim MAX811 MAX812 datasheet说明书
General DescriptionThe MAX811/MAX812 are low-power microprocessor (μP) supervisory circuits used to monitor power supplies in μP and digital systems. They provide excellent circuit reliability and low cost by eliminating external compo-nents and adjustments when used with 5Vpowered or 3V-powered circuits. The MAX811/MAX812 also provide a debounced manual reset input.These devices perform a single function: They assert a reset signal whenever the V CC supply voltage falls below a preset threshold, keeping it asserted for at least 140ms after V CC has risen above the reset threshold. The only difference between the two devices is that the MAX811 has an active-low RESET output (which is guaranteed to be in the correct state for V CC down to 1V), while the MAX812 has an active-high RESET output. The reset comparator is designed to ignore fast transients on V CC. Reset thresholds are available for operation with a variety of supply voltages.Low supply current makes the MAX811/MAX812 ideal for use in portable equipment. The devices come in a 4-pin SOT143 package.Applications●Computers●Controllers●Intelligent Instruments●Critical μP and μC Power Monitoring●Portable/Battery-Powered Equipment Benefits and Features●Integrated Voltage Monitor Increases SystemRobustness with Added Manual Reset• Precision Monitoring of 3V, 3.3V, and 5VPower-Supply Voltages• 140ms Min Power-On-Reset Pulse Width• RESET Output (MAX811), RESET Output(MAX812)• Guaranteed Over Temperature• Guaranteed RESET Valid to V CC = 1V (MAX811)• Power-Supply Transient Immunity●Saves Board Space• No External Components• 4-Pin SOT143 Package●Low Power Consumption Simplifies Power-SupplyRequirements• 6μA Supply Current*This part offers a choice of five different reset threshold voltages.

These μP supervisory circuits assert reset to prevent code execution errors during power-up, power-down, or brownout conditions.RESET is guaranteed to be a logic low for V CC> 1V. Once V CC exceeds the reset threshold, an internal timer keeps RESET low for the reset timeout period; after this interval, RESET goes high.If a brownout condition occurs (V CC dips below the reset threshold), RESET goes low. Any time V CC goes below the reset threshold, the internal timer resets to zero, and RESET goes low. The internal timer starts after V CC returns above the reset threshold, and RESET remains low for the reset timeout period.The manual reset input (MR) can also initiate a reset. See the Manual Reset Input section.The MAX812 has an active-high RESET output that is the inverse of the MAX811’s RESET output.Manual Reset InputMany μP-based products require manual reset capabil-ity, allowing the operator, a test technician, or external logic circuitry to initiate a reset. A logic low on MR asserts reset. Reset remains asserted while MR is low, and for the Reset Active Timeout Period (t RP) after MR returns high. This input has an internal 20kΩ pull-up resistor, so it can be left open if it is not used. MR can be driven with TTL or CMOS-logic levels, or with open-drain/collector outputs. Connect a normally open momentary switch from MR to GND to create a manual-reset function; external debounce circuitry is not required. If MR is driven from long cables or if the device is used in a noisy environment, connecting a 0.1μF capacitor from MR to ground provides additional noise immunity.Reset Threshold AccuracyThe MAX811/MAX812 are ideal for systems using a 5V ±5% or 3V ±5% power supply with ICs specified for 5V ±10% or 3V ±10%, respectively. They are designed to meet worst-case specifications over temperature. The reset is guaranteed to assert after the power supply falls out of regulation, but before power drops below the minimum specified operating voltage range for the system ICs. The thresholds are pre-trimmed and exhibit tight dis-tribution, reducing the range over which an undesirable reset may occur.PINNAME FUNCTION MAX811MAX81211GND Ground2—RESET Active-Low Reset Output. RESET remains low while V CC is below the reset threshold or while MR is held low. RESET remains low for the Reset Active Timeout Period (t RP) after the reset conditions are terminated.—2RESET Active-High Reset Output. RESET remains high while V CC is below the reset threshold or while MR is held low. RESET remains high for Reset Active Timeout Period (t RP) after the reset conditions are terminated.33MR Manual Reset Input. A logic low on MR asserts reset. Reset remains asserted as long as MR is low and for 180ms after MR returns high. This active-low input has an internal 20kΩpull-up resistor. It can be driven from a TTL or CMOS-logic line, or shorted to ground with a switch. Leave open if unused.44V CC+5V, +3.3V, or +3V Supply Voltage with Manual Reset InputPin DescriptionApplications InformationNegative-Going V CC TransientsIn addition to issuing a reset to the μP during power-up, power-down, and brownout conditions, the MAX811/ MAX812 are relatively immune to short duration negative-going V CC transients (glitches).Figure 1 shows typical transient durations vs. reset com-parator overdrive, for which the MAX811/MAX812 do not generate a reset pulse. This graph was generated using a negative-going pulse applied to V CC, starting above the actual reset threshold and ending below it by the magnitude indicated (reset comparator overdrive). The graph indicates the typical maximum pulse width a negative-going V CC transient may have without causing a reset pulse to be issued. As the magnitude of the tran-sient increases (goes farther below the reset threshold), the maximum allowable pulse width decreases. Typically, a V CC transient that goes 125mV below the reset thresh-old and lasts 40μs or less (MAX81_L/M) or 20μs or less (MAX81_T/S/R) will not cause a reset pulse to be issued.A 0.1μF capacitor mounted as close as possible to V CC provides additional transient immunity.Ensuring a Valid RESET OutputDown to V CC = 0VWhen V CC falls below 1V, the MAX811 RESET output no longer sinks current—it becomes an open circuit. Therefore, high-impedance CMOS-logic inputs connected to the RESET output can drift to undetermined voltages. This presents no problem in most applications, since most μP and other circuitry is inoperative with V CC below 1V. However, in applications where the RESET output must be valid down to 0V, adding a pulldown resistor to the RESET pin will cause any stray leakage currents to flow to ground, holding RESET low (Figure 2). R1’s value is not critical; 100kΩ is large enough not to load RESET and small enough to pull RESET to ground.A 100kΩ pull-up resistor to V CC is also recommended for the MAX812 if RESET is required to remain valid for V CC < 1V.Figure 1. Maximum Transient Duration without Causing a Reset Pulse vs. Comparator Overdrive Figure 2. RESET Valid to V CC = Ground Circuitwith Manual Reset InputInterfacing to μPs with Bidirectional Reset PinsμPs with bidirectional reset pins (such as the Motorola 68HC11 series) can contend with the MAX811/MAX812 reset outputs. If, for example, the MAX811 RESET output is asserted high and the μP wants to pull it low, indeter -minate logic levels may result. To correct such cases, connect a 4.7kΩ resistor between the MAX811 RESET (or MAX812 RESET) output and the μP reset I/O (Figure 3). Buffer the reset output to other system components.Figure 3.
