ISO 2768-1-1989中文版

2768-1初版1989-11-15常规公差——第一部分:无单独公差标示的线尺度、角度公差参考号ISO2768-1:1989(E) ISO 2768-1:1989(E)前言ISO(国际标准化组织)是世界范围内国家标准实体(ISO成员)的联合体。

通常由ISO技术委员会制定国际标准。

但是,只要对该组织建立的某个主题感兴趣,任何成员都可以在这方面充当委员会的代表。

所有与ISO关联的国际组织,政府以及非政府机构,都参加此项工作。

ISO在电工标准事务上,与国际电工委员会紧密一致。

由技术委员会起草的国际标准草稿,在ISO将其作为国际标准正式文件之前,需要分发给各成员实体进行核准。

标准的核准需要经过ISO的程序进行,即需要所有成员的75%赞成才可获得通过。

ISO2768-2由技术委员会ISO/TC 3(误差与配合)制定。

ISO2678-1初版与ISO2678-1:1989一起取代了ISO2768:1973。

题为常规公差的ISO2768包括以下部分:第一部分:无单独公差标示的线尺度、角度公差第二部分:无单独公差标示的部件几何公差ISO2768中附录A与B仅供参考。

简介所有部件部分的零部件都有自己的尺寸和几何形状。

如果尺寸或几何特性(形状,方向与位置)出现偏差,超出了该部分要求的最低值,则破坏了该部分的功能。

图纸上的公差规定应当完整,以确保控制零部件的尺寸与几何因素,也就是,不应该留给车间或检验部人员来判断。

使用尺寸与几何常规公差,减轻了满足该必要条件的任务。

国际标准 ISO2768-1:1989(E)常规公差——第一部分:无单独公差标示的线尺度、角度公差1 应用范围ISO2768的这部分意在简化图纸标示,规范常规线尺度、角度公差,从而使图纸上所有零部件不再出现单独不同的公差。

此处分四类进行公差规定。

注1:对常规线尺度、角度公差规定的方案,将在附件A中阐述。

该部分主要适用于金属材料切除后生产的或由金属板加工的零部件。

However, if the voltage across the Triac, V D , increases faster than rated dV/dt, the Triac may turn on. To avoid this situation, please incorporate a snubber circuit. Due to the many different types of load that can be driven, we can merely recommend some circuit vales to start with : Cs=0.022µF and Rs=47Ω. The operation of the SSR and snubber circuit should be tested and if unintentional switching occurs, please adjust the snubber circuit component values accordingly.When making the transition from On to Off state, a snubber circuit should be used ensure that sudden drops in current are not accompanied by large instantaneous changes in voltage across the Triac.This fast change in voltage is brought about by the phase difference between current and voltage. Primarily, this is experienced in driving loads which are inductive such as motors and solenoids. Following the procedure outlined above should provide sufficient results. For over voltage protection, a Varistor may be used.Any snubber or Varistor used for the above mentioned scenarios should be located as close to the main out-put triac as possible.Particular attention needs to be paid when utilizing SSRs that incorporate zero crossing circuitry.If the phase difference between the voltage and the current at the output pins is large enough, zero crossing type SSRs cannot be used. The result, if zero crossing SSRs are used under this condition, is that the SSR may not turn on and off irregardless of the input current. In this case, only a non zero cross type SSR should be used in combination with the above mentioned snubber circuit selection process.The load current should be within the bounds of derating curve. (Refer to Fig.2) Also, please use the optional heat sink when necessary.In case the optional heat sink is used and the isolation voltage between the device and the optional heat sink is needed, please locate the insulation sheet between the device and the heat sink.When the optional heat sink is equipped, please set up the M3 screw-fastening torque at 0.3 to 0.5N•m.In order to dissipate the heat generated from the inside of device effectively, please follow the below sugges-tions.● Design guide● Recommended Operating ConditionsParameterS108T02S208T02Symbol Unit InputOutputInput signal current at ON state Input signal current at OFF state Load supply voltage Load supply currentFrequencyOperating temperatureI F (ON)I F (OFF)V OUT (rms)I OUT (rms)f T oprmA mA V mA Hz ˚C−−−Locate snubber circuit between output terminals(Cs =0.022µF, Rs =47Ω)−−Conditions(∗) See Fig.2 about derating curve (I T (rms) vs. ambient temperature).16080800.147−20240.1120240I T (rms)×80%(∗)6380MIN.MAX.✩ For additional design assistance, please review our corresponding Optoelectronic Application Notes.● Standard CircuitV +V S108T02● DegradationIn general, the emission of the IRED used in SSR will degrade over time.In the case where long term operation and / or constant extreme temperature fluctuations will be applied to the devices, please allow for a worst case scenario of 50% degradation over 5years.Therefore in order to maintain proper operation, a design implementing these SSRs should provide at least twice the minimum required triggering current from initial operation.(a) Make sure there are no warps or bumps on the heat sink, insulation sheet and device surface.(b) Make sure there are no metal dusts or burrs attached onto the heat sink, insulation sheet and device sur-face.(c) Make sure silicone grease is evenly spread out on the heat sink, insulation sheet and device surface.Silicone grease to be used is as follows;1) There is no aged deterioration within the operating temperature ranges.2) Base oil of grease is hardly separated and is hardly permeated in the device.3) Even if base oil is separated and permeated in the device, it should not degrade the function of a device. Recommended grease : G-746 (Shin-Etsu Chemical Co., Ltd.): G-747 (Shin-Etsu Chemical Co., Ltd.): SC102 (Dow Corning Toray Silicone Co., Ltd.) In case the optional heat sink is screwed up, please solder after screwed.In case of the lead frame bending, please keep the following minimum distance and avoid any mechanical stress between the base of terminals and the molding resin.Some of AC electromagnetic counters or solenoids have built-in rectifier such as the diode.In this case, please use the device carefully since the load current waveform becomes similar with rectangu-lar waveform and this results may not make a device turn off.■ Manufacturing Guidelines● Soldering MethodFlow Soldering (No solder bathing)Flow soldering should be completed below 260˚C and within 10s.Preheating is within the bounds of 100 to 150˚C and 30 to 80s.Please solder within one time.Other noticesPlease test the soldering method in actual condition and make sure the soldering works fine, since the impact on the junction between the device and PCB varies depending on the tooling and soldering conditions.分销商库存信息:SHARP-MICROELECTRONICSS108T02S108T02F S208T02。

Squeeze and slide the stainless-steel yarn guides onto opposite sides of the flyer arms.NOTE: when spinning at higher RPM it may be necessary tosqueeze and rotate whichever yarn guide isn’t being used to achieve perfect balance.4. Apply a drop of oil to the flyer spindle and slide the bobbin on.1. Locate the two Orifice Reducer Bushes into the holes in top of the base.2. Locate the threading hook into the tapered hole in the front. This will only be required when using the Orifice Reducer Bushes.35. Locate the drive band onto the MIDDLE groove in the bobbinControls4Changing the bobbin- Turn the motor off using the ON/OFF switch or foot switch.- Remove the drive band from the motor pulley.- Slide the bobbin off the flyer spindle.- Apply a drop of oil to the spindle and fit anotherbobbin. Locate the drive band onto the MIDDLE groove in the bobbin whorl. Do not use the large groove as this will stretch the drive band.- Apply a drop of oil to the front of the flyer shaft. Position it under the leather brake band and into the front and rear flyer bearings.Orifice Reducer Bushes- Use the large Orifice Reducer Bush to reduce the orifice from 27mm (1⅛”) to 15mm (⅝”) for spinning medium yarns.- Use the small Orifice Reducer Bush to reduce the orifice to 9mm (⅜”) for spinning fine yarns.- Orifice Reducer Bushes help prevent the yarn vibrating. By drafting the yarn at about a 45-degree angle to the orifice the vibration will almost be eliminated.- When not in use store the bushes in the holes in top of the base.- Apply Vaseline to the o-ring to make them easier to Because the e-Spinner Super Jumbo is bobbin lead the yarn needs to be strong enough to turn the flyer. Thus, it requires very little tension on the leather brake band. At full speed the flyer rotates at approx. 500 RPM.1. Tie a piece of medium to thick wool yarn called a leader, approx. 1.5m (5 feet) long to the bobbin. Thread it through the flyer yarn guides with the black inserts on the left-hand side of the flyer and out through the orifice.SpinningAccessories - Available from your local Ashford Dealer.1. Thread the leader through the flyer yarn guide with the black inserts and out through the orifice. Locate 2 bobbins of spun yarn onto the pins of the optional Lazy Kate and tie the two strands of yarn to the leader.2. Check the SPIN/PLY switch is on PLY (up) and the SPEED control is on SLOW.

This combination lowers system cost, reduces board space requirements, and increases reliability.Applying power to the device activates the power on reset circuit which holds RESET/RESET active for a period of time. This allows the power supply and oscil-lator to stabilize before the processor executes code. The Watchdog Timer provides an independent protec-tion mechanism for microcontrollers. When the micro-controller fails to restart a timer within a selectable time out interval, the device activates the RESET/ RESET signal. The user selects the interval from three preset values. Once selected, the interval does not change, even after cycling the power.The device’s low V CC detection circuitry protects the user’s system from low voltage conditions, resetting the system when V CC falls below the minimum V CC trip point. RESET/RESET is asserted until V CC returns to proper operating level and stabilizes. Five industry standard V TRIP thresholds are available, however, Xicor’s unique circuits allow the threshold to be repro-grammed to meet custom requirements or to fine-tune the threshold for applications requiring higher precision.BLOCK DIAGRAMSISOSCK CS/WDIV CC RESET/RESETWPX5043 = RESETX5045 = RESET 元器件交易网X5043/X5045The memory portion of the device is a CMOS Serial EEPROM array with Xicor’s block lock protection. The array is internally organized as x 8. The device features a Serial Peripheral Interface (SPI) and software proto-col allowing operation on a simple four-wire bus.The device utilizes Xicor’s proprietary Direct Write™cell, providing a minimum endurance of 1,000,000 cycles and a minimum data retention of 100 years.PIN CONFIGURATIONPIN DESCRIPTIONSSerial Output (SO)SO is a push/pull serial data output pin. During a read cycle, data is shifted out on this pin. Data is clocked out by the falling edge of the serial clock.Serial Input (SI)SI is the serial data input pin. All opcodes, byte addresses, and data to be written to the memory are input on this pin. Data is latched by the rising edge of the serial clock.Serial Clock (SCK)The Serial Clock controls the serial bus timing for data input and output. Opcodes, addresses, or data present on the SI pin is latched on the rising edge of the clock input, while data on the SO pin changes after the fall-ing edge of the clock input.Chip Select (CS)When CS is high, the X5043/45 is deselected and the SO output pin is at high impedance and, unless an internal write operation is underway, the X5043/45 will be in the standby power mode. CS low enables the X5043/45, placing it in the active power mode. It should be noted that after power-up, a high to low transition on CS is required prior to the start of any operation.Write Protect (WP)When WP is low, nonvolatile writes to the X5043/45 are disabled, but the part otherwise functions normally. When WP is held high, all functions, including non vol-atile writes operate normally. WP going low while CS is still low will interrupt a write to the X5043/45. If the internal write cycle has already been initiated, WP going low will have no affect on a write.Reset (RESET, RESET)X5043/45, RESET/RESET is an active low/HIGH, open drain output which goes active whenever V CC falls below the minimum V CC sense level. It will remain active until V CC rises above the minimum V CC sense level for 200ms. RESET/RESET also goes active if the Watchdog timer is enabled and CS remains either high or low longer than the Watchdog time out period. A fall-ing edge of CS will reset the watchdog timer.PIN NAMESSymbol DescriptionCS Chip Select InputSO Serial OutputSI Serial InputSCK Serial Clock InputWP Write Protect InputV SS GroundV CC Supply VoltageRESET/RESET Reset Output 元器件交易网X5043/X5045PRINCIPLES OF OPERATIONPower On ResetApplication of power to the X5043/X5045 activates a Power On Reset Circuit. This circuit pulls the RESET/ RESET pin active. RESET/RESET prevents the sys-tem microprocessor from starting to operate with insuf-ficient voltage or prior to stabilization of the oscillator. When V CC exceeds the device V TRIP value for 200ms (nominal) the circuit releases RESET/RESET, allowing the processor to begin executing code.Low Voltage MonitoringDuring operation, the X5043/X5045 monitors the V CC level and asserts RESET/RESET if supply voltage falls below a preset minimum V TRIP. The RESET/RESET signal prevents the microprocessor from operating in a power fail or brownout condition. The RESET/RESET signal remains active until the voltage drops below 1V. It also remains active until V CC returns and exceeds V TRIP for 200ms.Watchdog TimerThe Watchdog Timer circuit monitors the microproces-sor activity by monitoring the WDI input. The micropro-cessor must toggle the CS/WDI pin periodically to prevent an active RESET/RESET signal. The CS/WDI pin must be toggled from HIGH to LOW prior to the expiration of the watchdog time out period. The state of two nonvolatile control bits in the Status Register determines the watchdog timer period. The micropro-cessor can change these watchdog bits. With no microprocessor action, the watchdog timer control bits remain unchanged, even during total power failure.V CC Threshold Reset ProcedureThe X5043/X5045 is shipped with a standard V CC threshold (V TRIP) voltage. This value will not change over normal operating and storage conditions. How-ever, in applications where the standard V TRIP is not exactly right, or if higher precision is needed in the V TRIP value, the X5043/X5045 threshold may be adjusted. The procedure is described below, and uses the application of a high voltage control signal.Setting the V TRIP VoltageThis procedure is used to set the V TRIP to a higher volt-age value. For example, if the current V TRIP is 4.4V and the new V TRIP is 4.6V, this procedure will directly make the change. If the new setting is to be lower than the current setting, then it is necessary to reset the trip point before setting the new value.T o set the new V TRIP voltage, apply the desired V TRIP threshold voltage to the V CC pin and tie the WP pin to the programming voltage V P. Then send a WREN com-mand, followed by a write of Data 00h to address 01h. CS going HIGH on the write operation initiates the V TRIP programming sequence. Bring WP LOW to com-plete the operation.Note: This operation also writes 00h to array address 01h.Figure 1. Set V TRIP Level Sequence (V CC = desired V TRIP value.)元器件交易网X5043/X5045Resetting the V TRIP VoltageThis procedure is used to set the V TRIP to a “native”voltage level. For example, if the current V TRIP is 4.4V and the new V TRIP must be 4.0V, then the V TRIP must be reset. When V TRIP is reset, the new V TRIP is some-thing less than 1.7V. This procedure must be used to set the voltage to a lower value.T o reset the V TRIP voltage, apply at least 3V to the V CC pin and tie the WP pin to the programming voltage V P. Then send a WREN command, followed by a write of Data 00h to address 03h. CS going HIGH on the write operation initiates the V TRIP programming sequence. Bring WP LOW to complete the operation.Note: This operation also writes 00h to array address 03h.Figure 2. Reset V TRIP Level Sequence (V CC > 3V. WP = 15–18V)Figure 3. Sample V TRIP Reset Circuit元器件交易网X5043/X5045Figure 4. V TRIP Programming SequenceSPI Serial MemoryThe memory portion of the device is a CMOS Serial EEPROM array with Xicor’s block lock protection. The array is internally organized as x8 bits. The device fea-tures a Serial Peripheral Interface (SPI) and software protocol allowing operation on a simple four-wire bus. The device utilizes Xicor’s proprietary Direct Write ™ cell, providing a minimum endurance of 1,000,000cycles and a minimum data retention of 100 years.The device is designed to interface directly with the synchronous Serial Peripheral Interface (SPI) of many popular microcontroller families.The device contains an 8-bit instruction register that controls the operation of the device. The instruction code is written to the device via the SI input. There are two write operations that requires only the instruction byte. There are two read operations that use the instruction byte to initiate the output of data. The remainder of the operations require an instruction byte,an 8-bit address, then data bytes. All instruction,address and data bits are clocked by the SCK input. All instructions (T able 1), addresses and data are trans-ferred MSB first.Clock and Data TimingData input on the SI line is latched on the first rising edge of SCK after CS goes LOW. Data is output on the SO line by the falling edge of SCK. SCK is static,allowing the user to stop the clock and then start it again to resume operations where left off. CS must be LOW during the entire operation.Table 1. Instruction Set Note:*Instructions are shown MSB in leftmost position.

This latch must be SET before a Write Operation is initiated. The WREN instruction will set the latch and the WRDI instruction will reset the latch (Figure 3). This latch is automatically reset upon a power-up condition and after the completion of a valid byte, page, or status register write cycle. The latch is also reset if WP is brought LOW.When issuing a WREN, WRDI or RDSR commands, it is not necessary to send a byte address or data.Figure 5. Write Enable/Disable Latch SequenceStatus RegisterThe Status Register contains four nonvolatile control bits and two volatile status bits. The control bits set the operation of the watchdog timer and the memory block lock protection. The Status Register is formatted as shown in “Status Register”.Status Register: (Default = 30H)The Write-In-Progress (WIP) bit is a volatile, read only bit and indicates whether the device is busy with an internal nonvolatile write operation. The WIP bit is read using the RDSR instruction. When set to a “1”, a non-volatile write operation is in progress. When set to a “0”, no write is in progress.The Write Enable Latch (WEL) bit indicates the status of the “write enable” latch. When WEL = 1, the latch is set and when WEL = 0 the latch is reset. The WEL bit is a volatile, read only bit. The WREN instruction sets the WEL bit and the WRDS instruction resets the WEL bit.The block lock bits, BL0 and BL1, set the level of block lock protection. These nonvolatile bits are programmed using the WRSR instruction and allow the user to pro-tect one quarter, one half, all or none of the EEPROM array. Any portion of the array that is block lock pro-tected can be read but not written. It will remain pro-tected until the BL bits are altered to disable block lock protection of that portion of memory.The Watchdog Timer bits, WD0 and WD1, select the Watchdog Time-out Period. These nonvolatile bits are programmed with the WRSR instruction.Read Status RegisterT o read the Status Register, pull CS low to select the device, then send the 8-bit RDSR instruction. Then the contents of the Status Register are shifted out on the SO line, clocked by CLK. Refer to the Read Status Register Sequence (Figure 6). The Status Register may be read at any time, even during a Write Cycle. Write Status RegisterPrior to any attempt to write data into the status regis-ter, the “Write Enable” Latch (WEL) must be set by issuing the WREN instruction (Figure 5). First pull CS LOW, then clock the WREN instruction into the device and pull CS HIGH. Then bring CS LOW again and enter the WRSR instruction followed by 8 bits of data.These 8 bits of data correspond to the contents of the status register. The operation ends with CS going HIGH. If CS does not go HIGH between WREN and WRSR, the WRSR instruction is ignored.7654321WD1WD0BL1BL0WELWIP1234567CSSI SCKHigh ImpedanceSOStatus Reg Bits Array Addresses ProtectedBL1BL0X5043/X504500None 01$180–$1FF 10$100–$1FF 11$000–$1FFStatus Register Bits Watchdog Time Out(Typical)WD1WD000 1.4 seconds 01600 milliseconds 10200 milliseconds 11disabled (factory default)Table 2.

The 8-bit READ instruction is transmitted to the device, followed by the 8-bit address. Bit 3 of the READ instruction selects the upper or lower half of the device. After the READ opcode and address are sent, the data stored in the memory at the selected address is shifted out on the SO line. The data stored in memory at the nextaddress can be read sequentially by continuing to pro-vide clock pulses. The address is automatically incre-mented to the next higher address after each byte of data is shifted out. When the highest address is reached, the address counter rolls over to address $000 allowing the read cycle to be continued indefi-nitely. The read operation is terminated by taking CS high. Refer to the Read EEPROM Array Sequence (Figure 8).Figure 8. Read EEPROM Array SequenceWrite Memory ArrayPrior to any attempt to write data into the memory array, the “Write Enable” Latch (WEL) must be set by issuing the WREN instruction (Figure 5). First pull CS LOW, then clock the WREN instruction into the device and pull CS HIGH. Then bring CS LOW again and enter the WRITE instruction followed by the 8-bit address and then the data to be written. Bit 3 of the WRITE instruction contains address bit A8, which selects the upper or lower half of the array. If CS does not go HIGH between WREN and WRITE, the WRITE instruction is ignored.The WRITE operation requires at least 16 clocks. CS must go low and remain low for the duration of the operation. The host may continue to write up to 16 bytes of data. The only restriction is that the 16 bytes must reside within the same page. A page address begins with address [x xxxx 0000] and ends with [x xxxx 1111]. If the byte address reaches the last byte on the page and the clock continues, the counter will roll back to the first address of the page and overwrite any data that has been previously written.For the write operation (byte or page write) to be com-pleted, CS must be brought HIGH after bit 0 of the last complete data byte to be written is clocked in. If it is brought HIGH at any other time, the write operation will not be completed (Figure 9).While the write is in progress following a status register or memory array write sequence, the Status Register may be read to check the WIP bit. WIP is HIGH while the nonvolatile write is in progress.Figure 9.

This combination lowers system cost, reduces board space requirements, and increases reliability.The user’s system is protected from low voltage condi-tions by the devices low Vcc detection circuitry. When Vcc falls below the minimum Vcc trip point, the system is reset. RESET/RESET is asserted until Vcc returns to proper operating levels and stabilizes.The memory portion of the device is a CMOS Serial E2PROM array with Xicor’s Block Lock TM Protection. The array is internally organized as x 8. The device features a Serial Peripheral Interface (SPI) and software protocol allowing operation on a simple four-wire bus.The device utilizes Xicor’s proprietary Direct Write TM cell, providing a minimum endurance of 100,000 cycles per sector and a minimum data retention of 100 years.BLOCK DIAGRAMRESET/RESET7036 FRM 01元器件交易网X25648/49, X25328/29, X25168/69PIN DESCRIPTIONSSerial Output (SO)SO is a push/pull serial data output pin. During a read cycle, data is shifted out on this pin. Data is clocked out by the falling edge of the serial clock.Serial Input (SI)SI is a serial data input pin. All opcodes, byte addresses, and data to be written to the memory are input on this pin. Data is latched by the rising edge of the serial clock. Serial Clock (SCK)The Serial Clock controls the serial bus timing for data input and output. Opcodes, addresses, or data present on the SI pin are latched on the rising edge of the clock input, while data on the SO pin change after the falling edge of the clock input.Chip Select (CS)When CS is HIGH, the device is deselected and the SO output pin is at high impedance and unless a nonvolatile write cycle is underway, the device will be in the standby power mode. CS LOW enables the device, placing it in the active power mode. It should be noted that after power-up, a HIGH to LOW transition on CS is required prior to the start of any operation.Write Protect (WP)When WP is low and the nonvolatile bit WPEN is “1”, nonvolatile writes to the device Status Register are disabled, but the part otherwise functions normally. When WP is held high, all functions, including nonvolatile writes to the Status Register operate normally. If an internal Status Register Write Cycle has already been initiated, WP going low while WPEN is a “1” will have no effect on this write. Subsequent write attempts to the Status Register under these conditions will be disabled.The WP pin function is blocked when the WPEN bit in the Status Register is “0”. This allows the user to install the device in a system with WP pin grounded and still be able to program the Status Register. The WP pin functions will be enabled when the WPEN bit is set to a “1”.Reset (RESET/RESET)RESET/RESET is an active LOW/HIGH, open drain out-put which goes active whenever Vcc falls below the mini-mum Vcc sense level. It will remain active until Vcc rises above the minimum Vcc sense level for 200ms.

The device contains an 8-bit instruction register. It is accessed via the SI input, with data being clocked in on the rising edge of SCK. CS must be LOW during the entire operation.All instructions (T able 1), addresses and data are trans-ferred MSB first. Data input on the SI line is latched on the first rising edge of SCK after CS goes LOW. Data is out-put on the SO line by the falling edge of SCK. SCK is static, allowing the user to stop the clock and then start it again to resume operations where left off.Write Enable LatchThe device contains a Write Enable Latch. This latch must be SET before a Write Operation is initiated. The WREN instruction will set the latch and the WRDI instruction will reset the latch (Figure 3). This latch is automatically reset upon a power-up condition and after the completion of a valid Write Cycle.Status RegisterThe RDSR instruction provides access to the Status Reg-ister. The Status Register may be read at any time, even during a Write Cycle. The Status Register is formatted as follows:The Write-In-Progress (WIP) bit is a volatile, read only bit and indicates whether the device is busy with an internal nonvolatile write operation. The WIP bit is read using the RDSR instruction. When set to a “1”, a nonvolatile write operation is in progress. When set to a “0”, no write is in progress.The Write Enable Latch (WEL) bit indicates the Status of the Write Enable Latch. When WEL=1, the latch is set HIGH and when WEL=0 the latch is reset LOW. The WEL bit is a volatile, read only bit. It can be set by the WREN instruction and can be reset by the WRDS instruction.The Block Lock bits, BL0 and BL1, set the level of Block Lock TM Protection. These nonvolatile bits are pro-grammed using the WRSR instruction and allow the user to protect one quarter, one half, all or none of the E 2 PROM array . Any portion of the array that is Block Lock Protected can be read but not written. It will remain pro-tected until the BL bits are altered to disable Block Lock Protection of that portion of memory. 7036 FRM T03Bits 4 and 5 of the Status Register will be read as “1’s”and must be written as “1’s” on all Status Register writes.7654321WPEN FLB11BL1BL0WELWIP7036 FRM T02Status Register Bits Array Addresses Protected BL1BL0X2564XX2532XX2516X00NoneNoneNone01$1800–$1FFF $0C00–$0FFF $0600–$07FF 10$1000–$1FFF $0800–$0FFF $0400–$07FF 11$0000–$1FFF $0000–$0FFF $0000–$07FFTable 1.

The Flag bit is automatically reset upon power up.The nonvolatile WPEN bit is programmed using the WRSR instruction. This bit works in conjunction with the WP pin to provide Programmable Hardware Write Protec-tion (T able 2). When WP is LOW and the WPEN bit is pro-grammed HIGH, all Status Register Write Operations are disabled.In Circuit Programmable ROM ModeThis mechanism protects the Block Lock and Watchdog bits from inadvertant corruption. It may be used to per-form an In Circuit Programmable ROM function by hard-wiring the WP pin to ground, writing and Block Locking the desired portion of the array to be ROM, and then pro-gramming the WPEN bit HIGH.Read SequenceWhen reading from the E 2 PROM memory array, CS is first pulled low to select the device. The 8-bit READ instruction is transmitted to the device, followed by the 16-bit address. After the READ opcode and address are sent, the data stored in the memory at the selected address is shifted out on the SO line. The data stored in memory at the next address can be read sequentially by continuing to provide clock pulses. The address is auto-matically incremented to the next higher address after each byte of data is shifted out. When the highest address is reached, the address counter rolls over to address $0000 allowing the read cycle to be continued indefinitely.The read operation is terminated by taking CS high. Refer to the Read E 2 PROM Array Sequence (Figure 1).T o read the Status Register, the CS line is first pulled low to select the device followed by the 8-bit RDSR instruc-tion. After the RDSR opcode is sent, the contents of the Status Register are shifted out on the SO line. Refer to the Read Status Register Sequence (Figure 2).Write SequencePrior to any attempt to write data into the device, the “Write Enable” Latch (WEL) must first be set by issuing the WREN instruction (Figure 3). CS is first taken LOW,then the WREN instruction is clocked into the device.After all eight bits of the instruction are transmitted, CS must then be taken HIGH. If the user continues the Write Operation without taking CS HIGH after issuing the WREN instruction, the Write Operation will be ignored.T o write data to the E 2 PROM memory array, the user then issues the WRITE instruction followed by the 16 bit address and then the data to be written. Any unused bits are specified to be “0’s”. The WRITE operation minimally takes 32 clocks. CS must go low and remain low for the duration of the operation. If the address counter reaches the end of a page and the clock continues, the counter will roll back to the first address of the page and overwrite any data that may have been previously written.For the Page Write Operation (byte or page write) to be completed, CS can only be brought HIGH after bit 0 of the last data byte to be written is clocked in. If it is brought HIGH at any other time, the write operation will not be completed (Figure 4).T o write to the Status Register, the WRSR instruction is followed by the data to be written (Figure 5). Data bits 0and 1 must be “0”. Data bits 4 and 5 must be “1”.Table 2. 7036 FRM T06STATUS REGISTER STATUS REGISTER DEVICE PIN BLOCK BLOCK STATUS REGISTER WELWPENWP#PROTECTED BLOCKUNPROTECTEDBLOCKWPEN, BL0, BL1 BITS0X X Protected Protected Protected 110Protected Writable Protected 10X Protected Writable Writable 1X1ProtectedWritableWritable元器件交易网X25648/49, X25328/29, X25168/69While the write is in progress following a Status Register or E 2 PROM Sequence, the Status Register may be read to check the WIP bit. During this time the WIP bit will be high.RESET/RESET OperationThe RESET (X25XX3) output is designed to go LOW whenever V CC has dropped below the minimum trip point,V trip .The RESET (X25XX5) output is designed to go HIGH whenever V CC has dropped below the minimum trip point,V trip.The RESET/RESET output is an open drain output and requires a pull up resistor.Operational NotesThe device powers-up in the following state:•The device is in the low power standby state.• A HIGH to LOW transition on CS is required to enter an active state and receive an instruction.•SO pin is high impedance.•The Write Enable Latch is reset.•The Flag Bit is reset.•Reset Signal is active for t PURST .Data ProtectionThe following circuitry has been included to prevent inad-vertent writes:• A WREN instruction must be issued to set the Write Enable Latch.•CS must come HIGH at the proper clock count in order to start a nonvolatile write cycle.Figure 1.

S88的内容与应用

S88的内容与应用

S88的内容与应用我们经常会在杂志期刊上看到S88或者ISA88的字样,可能大家会问:S88是什么?在仪表与流程工业起什么作用?本文试图从这两个方面来解答读者的困惑。

S88共有四个部分,分别是S88.01、S88.02、S88.03和S88.04。

下面就分别对他们做一个简单的介绍。

一、S88.011.一个国际工业标准S88.01标准的全称为ANSI/ISA-88.01-1995,批处理控制部分1:模型和术语,这一标准得到了国际上的广泛接受,它被开发并针对用于批处理工业。

2.批处理过程你会发现在化工与制药行业有很多批处理工艺,同样在食品、饮料和造纸也有这样的工艺,批处理过程的特点之一就是:如果把不同批次的产品放在一起的话,很难区分哪一批生产的产品;批处理的另一个特点是:用同一种设备可以生产出不同的最终产品。

这就是为什么对设备提出了高度柔性的要求了,S88标准为批处理控制提供了柔性的方法。

3.连续和离散过程虽然该标准是按批处理过程开发的,它也可适用于连续的和离散的过程上,连续过程的例子如:水的纯化和媒气获取;离散过程的例子如:汽车生产;如果这些的生产过程中需要一定程度的柔性,那么就可以应用S88。

4.在S88.01之前:“设备”使用程序的情况在批处理工业,设备用于在预处理阶段对原材料进行初步处理,通常这一过程需要程序对其进行控制,比如使用PLC。

从设备的物理能力来说,它还能够执行其他功能或执行已有功能的不同部分,但是,因为过程使用了程序代码,所以柔性的可能性有,但并不大。

如果要想使用同一个设备生产出不同的产品,你需要控制系统工程师的帮助,这也需要时间和金钱。

5.S88.01:模型和术语S88中包含了模型和术语,用来构建生产过程的结构,S88的主要概念是:把设备的控制和生产的过程相分离,这就使得:使用相同的设备,执行不同的过程,生产不同的产品成为可能。

6.物理模型S88.01提供了一种层叠模型,用来对物理设备进行结构化的描述,被称为物理模型。

ISO276811989中文版

国际标准ISO2768-1第一版1989-11-15常规公差——第一部份:无单独公差标示的线尺度、角度公差参考号ISO2768-1:1989(E)ISO 2768-1:1989(E)前言ISO(国际标准化组织)是世界范围内国家标准实体(ISO成员)的联合体。

通常由ISO技术委员会制定国际标准。

可是,只要对该组织成立的某个主题感爱好,任何成员都能够在这方面充当委员会的代表。

所有与ISO关联的国际组织,政府和非政府机构,都参加此项工作。

ISO在电工标准事务上,与国际电工委员会紧密一致。

由技术委员会起草的国际标准草稿,在ISO将其作为国际标准正式文件之前,需要分发给各成员实体进行核准。

标准的核准需要通过ISO的程序进行,即需要所有成员的75%同意才可取得通过。

ISO2768-2由技术委员会ISO/TC 3(误差与配合)制定。

ISO2678-1第一版与ISO2678-1:1989一路取代了ISO2768:1973。

题为常规公差的ISO2768包括以下部份:第一部份:无单独公差标示的线尺度、角度公差第二部份:无单独公差标示的部件几何公差ISO2768中附录A与B仅供参考。

简介所有部件部份的零部件都有自己的尺寸和几何形状。

假设是尺寸或几何特性(形状,方向与位置)显现误差,超出了该部份要求的最低值,那么破坏了该部份的功能。

图纸上的公差规定应当完整,以确保操纵零部件的尺寸与几何因素,也确实是,不该该留给车间或查验部人员来判定。

利用尺寸与几何常规公差,减轻了知足该必要条件的任务。

国际标准ISO2768-1:1989(E)常规公差——第一部份:无单独公差标示的线尺度、角度公差1 应用范围ISO2768的这部份意在简化图纸标示,标准常规线尺度、角度公差,从而使图纸上所有零部件再也不显现单独不同的公差。

此处分四类进行公差规定。

注1:对常规线尺度、角度公差规定的方案,将在附件A中论述。

该部份要紧适用于金属材料切除后生产的或由金属板加工的零部件。
