General DescriptionThe MAX13080E–MAX13089E +5.0V, ±15kV ESD-protect-ed, RS-485/RS-422 transceivers feature one driver and one receiver. These devices include fail-safe circuitry,guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance). The MAX13080E–MAX13089E include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.The MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX13083E/MAX13084E/MAX13085E also feature slew-rate-limited drivers but allow transmit speeds up to 500kbps. The MAX13086E/MAX13087E/MAX13088E driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX13089E slew rate is pin selectable for 250kbps,500kbps, and 16Mbps.The MAX13082E/MAX13085E/MAX13088E are intended for half-duplex communications, and the MAX13080E/MAX13081E/MAX13083E/MAX13084E/MAX13086E/MAX13087E are intended for full-duplex communica-tions. The MAX13089E is selectable for half-duplex or full-duplex operation. It also features independently programmable receiver and transmitter output phase through separate pins.The MAX13080E–MAX13089E transceivers draw 1.2mA of supply current when unloaded or when fully loaded with the drivers disabled. All devices have a 1/8-unit load receiver input impedance, allowing up to 256transceivers on the bus.The MAX13080E/MAX13083E/MAX13086E/MAX13089E are available in 14-pin PDIP and 14-pin SO packages.The MAX13081E/MAX13082E/MAX13084E/MAX13085E/MAX13087E/MAX13088E are available in 8-pin PDIP and 8-pin SO packages.

These devices feature fail-safe circuit-ry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all dri-vers disabled (see the Fail-Safe section). The MAX13080E/MAX13082E/MAX13083E/MAX13085E/ MAX13086E/MAX13088E/MAX13089E also feature a hot-swap capability allowing line insertion without erroneous data transfer (see the Hot Swap Capability section). The MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflec-tions caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX13083E/MAX13084E/MAX13085E also offer slew-rate limits allowing transmit speeds up to 500kbps. The MAX13086E/MAX13087E/MAX13088Es’ driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX13089E’s slew rate is selectable between 250kbps, 500kbps, and 16Mbps by driving a selector pin with a three-state driver.The MAX13082E/MAX13085E/MAX13088E are half-duplex transceivers, while the MAX13080E/MAX13081E/ MAX13083E/MAX13084E/MAX13086E/MAX13087E are full-duplex transceivers. The MAX13089E is selectable between half- and full-duplex communication by driving a selector pin (H/F) high or low, respectively.All devices operate from a single +5.0V supply. Drivers are output short-circuit current limited. Thermal-shutdown circuitry protects drivers against excessive power dissi-pation. When activated, the thermal-shutdown circuitry places the driver outputs into a high-impedance state.Receiver Input Filtering The receivers of the MAX13080E–MAX13085E, and the MAX13089E when operating in 250kbps or 500kbps mode, incorporate input filtering in addition to input hysteresis. This filtering enhances noise immunity with differential signals that have very slow rise and fall times. Receiver propagation delay increases by 25% due to this filtering.Fail-Safe The MAX13080E family guarantees a logic-high receiver output when the receiver inputs are shorted or open, or when they are connected to a terminated transmission line with all drivers disabled. This is done by setting the receiver input threshold between -50mV and -200mV. If the differential receiver input voltage (A - B) is greater than or equal to -50mV, RO is logic-high. If (A - B) is less than or equal to -200mV, RO is logic-low. In the case of a terminated bus with all transmitters disabled, the receiv-er’s differential input voltage is pulled to 0V by the termi-nation. With the receiver thresholds of the MAX13080E family, this results in a logic-high with a 50mV minimumnoise margin. Unlike previous fail-safe devices, the-50mV to -200mV threshold complies with the ±200mVEIA/TIA-485 standard.Hot-Swap Capability (Except MAX13081E/MAX13084E/MAX13087E)Hot-Swap InputsWhen circuit boards are inserted into a hot or powered backplane, differential disturbances to the data buscan lead to data errors. Upon initial circuit board inser-tion, the data communication processor undergoes itsown power-up sequence. During this period, the processor’s logic-output drivers are high impedanceand are unable to drive the DE and RE inputs of these devices to a defined logic level. Leakage currents up to±10µA from the high-impedance state of the proces-sor’s logic drivers could cause standard CMOS enableinputs of a transceiver to drift to an incorrect logic level. Additionally, parasitic circuit board capacitance couldcause coupling of V CC or GND to the enable inputs. Without the hot-swap capability, these factors could improperly enable the transceiver’s driver or receiver.When V CC rises, an internal pulldown circuit holds DElow and RE high. After the initial power-up sequence,the pulldown circuit becomes transparent, resetting thehot-swap tolerable input.Hot-Swap Input CircuitryThe enable inputs feature hot-swap capability. At theinput there are two NMOS devices, M1 and M2 (Figure 9). When V CC ramps from zero, an internal 7µstimer turns on M2 and sets the SR latch, which alsoturns on M1. Transistors M2, a 1.5mA current sink, andM1, a 500µA current sink, pull DE to GND through a5kΩresistor. M2 is designed to pull DE to the disabledstate against an external parasitic capacitance up to100pF that can drive DE high. After 7µs, the timer deactivates M2 while M1 remains on, holding DE low against three-state leakages that can drive DE high. M1 remains on until an external source overcomes the required input current. At this time, the SR latch resetsand M1 turns off. When M1 turns off, DE reverts to a standard, high-impedance CMOS input. Whenever V CCdrops below 1V, the hot-swap input is reset.For RE there is a complementary circuit employing two PMOS devices pulling RE to V CC. MAX13080E–MAX13089E+5.0V, ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversM A X 13080E –M A X 13089EMAX13089E ProgrammingThe MAX13089E has several programmable operating modes. Transmitter rise and fall times are programma-ble, resulting in maximum data rates of 250kbps,500kbps, and 16Mbps. To select the desired data rate,drive SRL to one of three possible states by using a three-state driver: V CC , GND, or unconnected. F or 250kbps operation, set the three-state device in high-impedance mode or leave SRL unconnected. F or 500kbps operation, drive SRL high or connect it to V CC .F or 16Mbps operation, drive SRL low or connect it to GND. SRL can be changed during operation without interrupting data communications.Occasionally, twisted-pair lines are connected backward from normal orientation. The MAX13089E has two pins that invert the phase of the driver and the receiver to cor-rect this problem. F or normal operation, drive TXP and RXP low, connect them to ground, or leave them uncon-nected (internal pulldown). To invert the driver phase,drive TXP high or connect it to V CC . To invert the receiver phase, drive RXP high or connect it to V CC . Note that the receiver threshold is positive when RXP is high.The MAX13089E can operate in full- or half-duplex mode. Drive H/F low, leave it unconnected (internal pulldown), or connect it to GND for full-duplex opera-tion. Drive H/F high for half-duplex operation. In full-duplex mode, the pin configuration of the driver and receiver is the same as that of a MAX13080E. In half-duplex mode, the receiver inputs are internally connect-ed to the driver outputs through a resistor-divider. This effectively changes the function of the device’s outputs.Y becomes the noninverting driver output and receiver input, Z becomes the inverting driver output and receiver input. In half-duplex mode, A and B are still connected to ground through an internal resistor-divider but they are not internally connected to the receiver.±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro-static discharges encountered during handling and assembly. The driver outputs and receiver inputs of the MAX13080E family of devices have extra protection against static electricity. Maxim’s engineers have devel-oped state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD struc-tures withstand high ESD in all states: normal operation,shutdown, and powered down. After an ESD event, the MAX13080E–MAX13089E keep working without latchup or damage.ESD protection can be tested in various ways. The transmitter outputs and receiver inputs of the MAX13080E–MAX13089E are characterized for protec-tion to the following limits:•±15kV using the Human Body Model•±6kV using the Contact Discharge method specified in IEC 61000-4-2ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 10a shows the Human Body Model, and Figure 10b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest,which is then discharged into the test device through a 1.5k Ωresistor.IEC 61000-4-2The IEC 61000-4-2 standard covers ESD testing and performance of finished equipment. However, it does not specifically refer to integrated circuits. The MAX13080E family of devices helps you design equip-ment to meet IEC 61000-4-2, without the need for addi-tional ESD-protection components.+5.0V , ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversThe major difference between tests done using the Human Body Model and IEC 61000-4-2 is higher peak current in IEC 61000-4-2 because series resistance is lower in the IEC 61000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 61000-4-2 is generally lower than that measured using the Human Body Model. Figure 10c shows the IEC 61000-4-2 model, and Figure 10d shows the current waveform for IEC 61000-4-2 ESD Contact Discharge test.Machine Model The machine model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. The objective is to emulate the stress caused when I/O pins are contacted by handling equipment during test and assembly. Of course, all pins require this protection, not just RS-485 inputs and outputs.Applications Information256 Transceivers on the BusThe standard RS-485 receiver input impedance is 12kΩ(1-unit load), and the standard driver can drive up to 32-unit loads. The MAX13080E family of transceivers has a1/8-unit load receiver input impedance (96kΩ), allowingup to 256 transceivers to be connected in parallel on one communication line. Any combination of these devices,as well as other RS-485 transceivers with a total of 32-unit loads or fewer, can be connected to the line.Reduced EMI and ReflectionsThe MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to250kbps. The MAX13083E/MAX13084E/MAX13085Eoffer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX13089E withSRL = V CC or unconnected are slew-rate limited. WithSRL unconnected, the MAX13089E error-free data transmission is up to 250kbps. With SRL connected toV CC,the data transmit speeds up to 500kbps. MAX13080E–MAX13089E+5.0V, ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversM A X 13080E –M A X 13089ELow-Power Shutdown Mode (Except MAX13081E/MAX13084E/MAX13087E)Low-power shutdown mode is initiated by bringing both RE high and DE low. In shutdown, the devices typically draw only 2.8µA of supply current.RE and DE can be driven simultaneously; the devices are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 700ns, the devices are guaranteed to enter shutdown.Enable times t ZH and t ZL (see the Switching Characteristics section) assume the devices were not in a low-power shutdown state. Enable times t ZH(SHDN)and t ZL(SHDN)assume the devices were in shutdown state. It takes drivers and receivers longer to become enabled from low-power shutdown mode (t ZH(SHDN), t ZL(SHDN))than from driver/receiver-disable mode (t ZH , t ZL ).Driver Output ProtectionTwo mechanisms prevent excessive output current and power dissipation caused by faults or by bus contention.The first, a foldback current limit on the output stage,provides immediate protection against short circuits over the whole common-mode voltage range (see the Typical Operating Characteristics ). The second, a thermal-shut-down circuit, forces the driver outputs into a high-imped-ance state if the die temperature exceeds +175°C (typ).Line LengthThe RS-485/RS-422 standard covers line lengths up to 4000ft. F or line lengths greater than 4000ft, use the repeater application shown in Figure 11.Typical ApplicationsThe MAX13082E/MAX13085E/MAX13088E/MAX13089E transceivers are designed for bidirectional data commu-nications on multipoint bus transmission lines. F igures 12 and 13 show typical network applications circuits. To minimize reflections, terminate the line at both ends in its characteristic impedance, and keep stub lengths off the main line as short as possible. The slew-rate-lim-ited MAX13082E/MAX13085E and the two modes of the MAX13089E are more tolerant of imperfect termination.Chip InformationTRANSISTOR COUNT: 1228PROCESS: BiCMOS+5.0V , ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversFigure 11.

The common mistakes are the wrong select of type of board or serial port etc.4 Get StartedGT2560 is the CPU of a 3D printer, manipulating the whole process of printing. GT2560 can’t be put in use directly without uploading firmware. 1. Firmware uploading- marlin. 2. Setting parameters of the firmwareThe parameters that need setting are as below, for those not mentioned just leave them as default.#define BAUDRATE 250000This parameter is for the baud rate of serial port. Note: a successful communication can be realizedonly when the Baud rate of upper computer is identical with that of Firmware. The Baud rate is not set in random. The common Baud rate are: 2400，9600，19200，38400，57600，115200，250000. The last three are frequently used for 3D Printer.#define MOTHERBOARD 7This parameter is set for board type. 3D Printer has many types of main board, and the settings of IOs are different, therefore, the parameter has to correspond to the type of your b oard, or it can’t operate normally. The parameter of GT2560 should be 7(single- nozzle). For other board, you can refer to the annotation on the board.#define TEMP_SENSOR_0 1#define TEMP_SENSOR_BED 1The two parameters are set for the type of temperature sensor respectively. They are the critical parameter to check if the sensor read temperature correctly. The printer can’t operate normally, even has potential risk (damage the device and even worse). You must modify depending on the temperature sensor you use.#define EXTRUDE_MINTEMP 170This parameter is set to avoid potential risks when the extruder operates before reaching the rated temperature. If you use other 3D Printer, such as printer to make Chocolates, 45℃is appropriate, so that the parameter configured to a lower value(such as 40℃).const bool X_ENDSTOPS_INVERTING = true; Tel: +86 755 2658 4110 Fax: +86 755 2658 4074 -858const bool Y_ENDSTOPS_INVERTING = true;const bool Z_ENDSTOPS_INVERTING = true.The three parameters are set for the end stops of three axes. If the configuration is true, the end stop outputs 1 in default condition, and outputs 0 when triggered. That is to say, mechanical end stop should connect to the NO (normally open) contactor. If it is connected to the NC (normally closed), true should be changed to false.#define INVERT_X_DIR false#define INVERT_Y_DIR trueMistakes are often made in the above two parameters. The parameters are different for different machinery. In principle, the origin should be at lower-left corner of the print platform (origin: [0, 0]), or at up-right corner (origin: [max, max]). Only in this way will the printing be correct, otherwise, the printing is the mirror image of one axis which is not what expected.#define X_HOME_DIR -1#define Y_HOME_DIR -1#define Z_HOME_DIR -1If the position of the origin is the minimum, the parameter is -1; if it is the maximum, the parameter is 1.#define X_MAX_POS 205#define X_MIN_POS 0#define Y_MAX_POS 205 Tel: +86 755 2658 4110 Fax: +86 755 2658 4074 -858#define Y_MIN_POS 0#define Z_MAX_POS 200#define Z_MIN_POS 0These parameters are crucial to the printing size. Fill in parameters by reference to the coordinate graphs. It is important to note that the origin is not the printing center and the real printing center usually lies at [(x.max - x.min)/2, (y.max -y.min/2)]. The coordinate of central will be used in the slice tool. The printing center’s coordinate must correspond to the parameter configuration, or it will print to the outside of the platform.#define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0}The parameter means the homing speeds (mm/min). This parameter can be set as default if you use the x-axis and y-axis adopt synchronous belt drive and z-axis adopts screw drive.#define DEFAULT_AXIS_STEPS_PER_UNIT {85.3333, 85.3333, 2560, 158.8308}These parameters are crucial to the printing size. These parameters indicate the pulse the axis need when operating 1mm. they are corresponding to x, y, z axis and extruder respectively. In most cases these figure should be calculated by yourself, you can refer to:http://calculator.josefprusa.cz/#steppers.So far, the commonest parameters have been configured and the printer can work now. In addition, if the 2004 LCD needs verifying, you should delete the “//” from “//#define REPRAP_DISCOUNT_SMART_CONTROLLER” to ensure the normal working. Tel: +86 755 2658 4110 Fax: +86 755 2658 4074 -8585 FAQ1. How many extruders can GT2560 support?At most 2 extruders, GT2560 supports 5 A4988 stepper motor drivers, they are X/Y/Z axis and 2 extruders.2. What is the power required?You need to use the 12V-24V power supply, and if you are using the single extruder one, the total power is no less than 200W, if you are using the dual extruder one, the total power is no less than 2 40W.3. The stepper motor on for the extruder doesn’t turn?By default in the firmware, only when the temperature of the extruder reaches 170°C can the moto r turn.

MAX2605-MAX2609中文资料

General DescriptionThe MAX2605–MAX2609 evaluation kits (EV kits) simplify evaluation of this family of voltage-controlled oscillators (VCOs). These kits enable testing of the devices’ per-formance and require no additional support circuitry.Both signal outputs use SMA connectors to facilitate connection to RF test equipment.These EV kits are fully assembled and tested. Their oscil-lation frequencies are set to approximately the midrange of the respective VCOs.Featureso Easy Evaluationo Complete, Tunable VCO Test Board with Tank Circuit o Low Phase Noiseo Fully Assembled and TestedEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits19-1673 Rev 0; 9/00Ordering InformationComponent SuppliersFor free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.MAX2606 Component ListMAX2605 Component ListE v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 2_______________________________________________________________________________________Quick StartThe MAX2605–MAX2609 evaluation kits are fully assembled and factory tested. Follow the instructions in the Connections a nd Setup section for proper device evaluation.Test Equipment Required•Low-noise power supplies (these are recommended for oscillator noise measurement). Noise or ripple will frequency-modulate the oscillator and cause spectral spreading. Batteries can be used in place of power supplies, if necessary.– Use a DC power supply capable of supplying +2.7V to +5.5V. Alternatively, use two or three 1.5V batteries.– Use a DC power supply capable of supplying +0.4V to +2.4V, continuously variable, for TUNE.Alternatively, use two 1.5V batteries with a resistive voltage divider or potentiometer.•An RF spectrum analyzer that covers the operating frequency range of the MAX2605–MAX2609• A 50Ωcoaxial cable with SMA connectors •An ammeter (optional)Connections and Setup1)Connect a DC supply (preset to +3V) to the V CC and GND terminals (through an ammeter, if desired) on the EV kit.2)Turn on the DC supply. If used, the ammeter readingMAX2607 Component ListMAX2608 Component ListEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits_______________________________________________________________________________________3approximates the typical operating current specified in the MAX2605–MAX2609 data sheet.3)Connect the VCO output (OUT+ or OUT-) to a spec-trum analyzer with a 50Ωcoaxial cable.4)Apply a positive variable DC voltage between 0.4V and 2.4V to TUNE.5)Check the tuning bandwidth on the spectrum analyz-er by varying the tuning voltage (+0.4V to +2.4V).Layout ConsiderationsThe EV kit PC board can serve as a guide for laying out a board using the MAX2605–MAX2609. Generally, the VCC pin on the PC board should have a decoupling capacitor placed close to the IC. This minimizes noisecoupling from the supply. Also, place the VCO as far away as possible from the noisy section of a larger sys-tem, such as a switching regulator or digital circuits.The VCO ’s performance is strongly dependent on the availability of the external tuning inductor. For best per-formance, use high-Q components and choose their val-ues carefully. To minimize the effects of parasitic ele-ments, which degrade circuit performance, place the tuning inductor and C BYP close to the VCO. For higher-frequency versions, include the parasitic PC board inductance and capacitance when calculating the oscillation frequency. In addition, remove the ground plane around and under the tuning inductor to minimize the effect of parasitic capacitance.Noise on TUNE translates into FM noise on the outputs;therefore, keep the trace between TUNE and the control circuitry as short as possible. If necessary, use an RC filter to further suppress noise, as done on the EV kits.E v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 4_______________________________________________________________________________________Figure 2.

ArduinoMega2560引脚说明以及功能剖析

ArduinoMega2560引脚说明以及功能剖析很早之前⼊⼿了⼀块Arduino Mega2560，当时只是认为其操作简单且更加⼈性化，开源⽅便，想了解了解。

最新搞项⽬想⽤Arduino试试控制8路舵机，但⽹上找的Servo库⼤多说只⽀持9，10接⼝，很是恼⽕(资料怎么写就怎么搬，到底是不是只⽀持9，10接⼝有⼏个知道?⼜有⼏个知道为什么?)。

了解Arduino的最好平台当然是官⽹，我相信官⽹肯定不会遗漏⾃⼰产品最有特⾊的东西，因此以它为参考绝对没错。

另外，必要部分辅助以百科，以及各位⼴⼤亲爱博友的资料(就不⼀⼀列举了，在此谢过)。

本⽂以Arduino Mega 2560为基础解释，其他板⼦都差不多。

⼀：概述 Arduino Mega 2560是基于ATmega2560的微控制板，有54路数字输⼊/输出端⼝(其中15个可以作为PWM输出)，16路模拟输⼊端⼝，4路UART串⼝，16MHz的晶振，USB连接⼝，电池接⼝，ICSP头和复位按钮。

简单地⽤USB连接电脑或者⽤交直流变压器就能使⽤。

Mega 2560 是Arduino Mega系列的升级版。

Mega 2560与之前的板⼦(最⼤)不同在于：它没⽤FTDI USB-to-serial驱动芯⽚，⽽是⽤ATmega16U2编程作为USB-to-serial传输器(V1版本使⽤8U2)。

The MAX306/MAX307 switches operate with ±4.5V to ±20V bipolar supplies or with a +4.5V to +30V single supply; connect V- to GND when operating with a single supply. Also, both device types can operate with unbalanced supplies such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)Overvoltage ProtectionProper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings because stresses beyond the listed rat-ings may cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by either the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage pro-tection (Figure 1). Adding diodes reduces the analogsignal range to 1V above V+ and 1V below V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and V- should not exceed +44V.M A X 306/M A X 307Precision, 16-Channel/Dual 8-Channel,High-Performance, CMOS Analog Multiplexers 6_______________________________________________________________________________________Output–bidirectionalCOM28Address Inputs A3–A014–17Enable InputsEN 18Analog Inputs–bidirectional NO1–NO819–26Negative Supply Voltage Input V-27Ground GND 12Analog Inputs–bidirectional NO16–NO94–11MAX306PINNo Internal Connections N.C.2, 3, 13Positive Supply Voltage Input V+1FUNCTIONNAME_____________________________________________________________Pin DescriptionsDiodesMAX306/MAX307Precision, 16-Channel/Dual 8-Channel,High-Performance, CMOS Analog Multiplexers_______________________________________________________________________________________7______________________________________________Test Circuits/Timing DiagramsM A X 306/M A X 307Precision, 16-Channel/Dual 8-Channel,High-Performance, CMOS Analog Multiplexers 8________________________________________________________________________________________________________________________Test Circuits/Timing Diagrams (continued)Figure 5.

Fujitsu PRIMERGY CX2560 M5 Multi-Node服务器数据表说明书

Data SheetFujitsu PRIMERGY CX2560 M5 Multi-Node ServerBalanced efficiency and expandability for demanding cloud and virtualization scenariosPRIMERGY CX2560 M5The Fujitsu Server PRIMERGY CX2560 M5 delivers the latest generation of powerful processors, large memory capacity and scalable I/O capability that meet virtualization, server consolidation or enterprise application needs. It’s a flexible, two-socket half-height/width server node for the PRIMERGY CX400 M4 chassis powered by Intel® Xeon® Scalable processors as well as new 2nd generation processors of the Intel® Xeon® Scalable Family (CLX-R) delivering industry-leadingfrequencies. Each CX2560 M5 within the enclosure supports up to 2TB of DDR4 memory, making it a perfect candidate for dense virtualization environments. Furthermore, it is possible to use new Intel® Optane™ DC Persistent Memory and to mix them with standard DDR4 modules, resulting in a total capacity of 7,680 GB per server. Unlike traditional DRAM, the new persistent memory modules will offer the unprecedented combination of high-capacity, affordability and persistence. Servers equipped with this new class of memory will be able to adapt and optimize their workloads by moving and maintaining larger amounts of data closer to the processor and minimizing the higher latency of fetching data from system storage. The CX2560 M5 storage options include six 2.5-inch SAS/SATA HDD/SSD drives per node, with additional option of using two M.2 drives or a dual microSD card directly in the system as an internal boot device. The PRIMERGY CX400 M4 chassis supports up to four CX2560 M5 servers.Features & BenefitsTechnical detailsPRIMERGY CX2560 M5Base unit PRIMERGY CX2560 M5 air coolingHousing types Air-cooled nodeProduct Type Dual Socket 1U Server NodeMainboardMainboard type D 3853Chipset Intel® C624Processor quantity and type 1 -

arduino2560简介

电源
Arduino Mega2560 可以通过 3 种方式供电，而且能自动选择供电方式外部直流电源通过电源插座供电。电池连接电源连接器的 GND 和 VIN 引脚。 USB 接口直接供电。
电源引脚说明 VIN --- 当外部直流电源接入电源插座时，可以通过 VIN 向外部供电；也可以通过此引脚向 Mega2560 直接供电；VIN 有电时将忽略从 USB 或者其他引脚接入的电源。 5V --- 通过稳压器或 USB 的 5V 电压，为 UNO 上的 5V 芯片供电。 3.3V --- 通过稳压器产生的 3.3V 电压，最大驱动电流 50mA。 GND --- 地脚。
存储器
ATmega2560 包括了片上 256KB Flash，其中 8KB 用于 Bootloader。同时还有 8KB SRAM 和 4KB EEPROM。
输入输出
1. 14 路数字输入输出口：工作电压为 5V，每一路能输出和接入最大电流为 40mA。每一路配置了 20-50K 欧姆内部上拉电阻（默认不连接)。除此之外，有些引脚有特定的功能 4 路串口信号：串口 0---0(RX)and 1(TX);串口 1---19(RX)and 18(TX);串口 2---17(RX)and 16(TX);串口 3---15(RX)and 14(TX)。其中串口 0 与内部 ATmega8U2 USB-to-TTL 芯片相连，提供 TTL 电压水平的串口接收信号。 6 路外部中断：2(中断 0)，3(中断 1)，18(中断 5)，19(中断 4)，20(中断 3)，and 21(中断 2)。触发中断引脚，可设成上升沿、下降沿或同时触发。 14 路脉冲宽度调制 PWM（0--13）：提供 14 路 8 位 PWM 输出。 SPI（53(SS)，51(MOSI)，50(MISO)，52(SCK)）：SPI 通信接口。 LED（13 号）：Arduino 专门用于测试 LED 的保留接口，输出为高时点亮 LED，反之输出为低时 LED 熄灭。
