AC measurements assume t T = 2ns.2. An initial pause of 100 is required after power up, and it followed by a minimum of eightinitialization cycles (RAS - only refresh cycle or CAS - before - RAS refresh cycle). If the internal refresh counter is used, a minimun of eight CAS - before - RAS refresh cycles are required.3. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device.4. All the V CC and V SS pins shall be supplied with the same voltages.5. t RAS (min) = t RWD (min)+t RWL (min)+t T in read-modify-write cycle.6. t CAS (min) = t CWD (min)+t CWL (min)+t T in read-modify-write cycle.7. t ASC (min), t RCS (min), t WCS (min), and t RPC are determined by the falling edge of CAS .8. t RCD (max) is specified as a reference point only, and t RAC (max) can be met with the t RCD (max) limit.Otherwise, t RAC is controlled exclusively by t CAC if t RCD is greater than the specified t RCD (max) limit. 9. t RAD (max) is specified as a reference point only, and t RAC (max) can be met with the t RAD (max) limit.Otherwise, t RAC is controlled exclusively by t AA if t RAD is greater than the specified t RAD (max) limit. 10. t CRP , t CHR , t RCH , t CPA and t CPW are determined by the rising edge of CAS .11. V IH (min) and V IL (max) are reference levels for measuring timing or input signals. Therefore, transitiontime is measured between V IH and V IL .12. Assumes that t RCD tRCD (max) and t RAD t RAD (max). If t RCD or t RAD is greater than the maximum recommended value shown in this table, t RAC exceeds the value shown. 13. Assumes that (max) and (max).14. Access time is determined by the maximum of t AA , t CAC , t CPA . 15. Assumes that (max) and (max). 16. Either t RCH or t RRH must be satisfied for a read cycle.17. t OFF (max) and t OEZ (max) define the time at which the output achieves the open circuit condition (highimpedance). t OFF is determined by the later rising edge of RAS or CAS.18. t WCS , t RWD , t CWD , and t AWD are not restrictive operating parameters. They are included in the datasheet as electrical characteristics only. If (min), the cycle is an early write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle.

INFORMATIONFigure9illustrates the basic circuit diagram for both the INA138and INA168.Load current I S is drawn from supply V S through shunt resistor R S.The voltage drop in shunt resistor V S is forced across R G1by the internal op amp,causing current to flow into the collector of Q1.External resistor R L converts the output current to a voltage, V OUT,at the OUT pin.The transfer function for the INA138is:I O=g m(V IN+−V IN−)where g m=200m A/V.In the circuit of Figure9,the input voltage,(V IN+−V IN−),is equal to IS x RS and the output voltage,V OUT,is equal to I O x R L.The transconductance,g m,of the INA138is200m A/V.The complete transfer function for the current measurement amplifier in this application is:V OUT=(I S)(R S)(200m A/V)(R L)The maximum differential input voltage for accurate measurements is0.5V,which produces a10m A output current.A differential input voltage of up to2V will not cause damage.Differential measurements(pins3and4) must be unipolar with a more-positive voltage applied to pin3.If a more-negative voltage is applied to pin3,the output current,I O,will be zero,but it will not cause damage.BASIC CONNECTIONFigure9shows the basic connection of the INA138.The input pins,V IN+and V IN−,should be connected as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistance.The output resistor,RL,is shown connected between pin1and ground.Best accuracy is achieved with the output voltage measured directly across R L.This is especially important in high-current systems where load current could flow in the ground connections,affecting the measurement accuracy.No power-supply bypass capacitors are required for stability of the INA138.However,applications with noisy or high-impedance power supplies may require decoupling capacitors to reject power-supply noise.Connect bypass capacitors close to the device pins.POWER SUPPLIESThe input circuitry of the INA138can accurately measure beyond its power-supply voltage,V+.For example,the V+power supply can be5V,whereas the load power supply voltage is up to+36V(or+60V with the INA168). The output voltage range of the OUT terminal,however,is limited by the lesser of the two voltages(see Output Voltage Range section).SELECTING R S AND R LThe value chosen for the shunt resistor,R S,depends on the application and is a compromise between small-signal accuracy and maximum permissible voltage loss in the measurement line.High values of R S provide better accuracy at lower currents by minimizing the effects of offset,while low values of RS minimize voltage loss in the supply line.For most applications,the best performance is attained with an R S value that provides a full-scale shunt voltage range of50mV to100mV.Maximum input voltage for accurate measurements is500 mV.R L is chosen to provide the desired full-scale output voltage.The output impedance of the INA138OUT terminal is very high which permits using values of R L up to500kΩwith excellent accuracy.The input impedance of any additional circuitry at the output should be much higher than the value of R L to avoid degrading accuracy.Some analog-to-digital(A/D)converters have input impedances that significantly affects measurement gain.The input impedance of the A/D converter can be included as part of the effective R L if its input can be modeled as a resistor to ground.Alternatively,an op amp can be used to buffer the A/D converter input.Figure9shows the recommended values of R L.6Submit Documentation Feedback Copyright©2003–2010,Texas Instruments IncorporatedINA138-Q1,IN168-Q1 SGLS174D–SEPTEMBER2003–REVISED DECEMBER2010Figure9.Basic Circuit ConnectionsOUTPUT VOLTAGE RANGEThe output of the INA138is a current,which is converted to a voltage by the load resistor,RL.The output current remains accurate within the compliance voltage range of the output circuitry.The shunt voltage and the input common-mode and power-supply voltages limit the maximum possible output swing.The maximum output voltage compliance is limited by the lower of the two equations below:V out max=(V+)−0.7V−(VIN+−V IN−)orV out max=V IN−−0.5V(whichever is lower)BANDWIDTHMeasurement bandwidth is affected by the value of the load resistor,R L.High gain produced by high values of R L yields a narrower measurement bandwidth(see the Typical Characteristics section).For widest possible bandwidth,keep the capacitive load on the output to a minimum.Reduction in bandwidth due to capacitive load is shown in the Typical Characteristics section.If bandwidth limiting(filtering)is desired,a capacitor can be added to the output(see Figure12).This will not cause instability.APPLICATIONSThe INA138is designed for current shunt measurement circuits,as shown in Figure9,but its basic function is useful in a wide range of circuitry.An engineer may find many unforeseen uses in measurement and level shifting circuits.A few ideas are illustrated in Figure10through Figure15.Copyright©2003–2010,Texas Instruments Incorporated Submit Documentation Feedback7INA138-Q1,IN168-Q1SGLS174D –SEPTEMBER 2003–REVISED DECEMBER 2010Figure 10.Buffering Output to Drive and A/DFigure 11.Output FilterFigure 12.Offsetting the Output Voltage8Submit Documentation Feedback Copyright ©2003–2010,Texas Instruments IncorporatedINA138-Q1,IN168-Q1 SGLS174D–SEPTEMBER2003–REVISED DECEMBER2010Figure13.Bipolar Current MeasurementCopyright©2003–2010,Texas Instruments Incorporated Submit Documentation Feedback9INA138-Q1,IN168-Q1SGLS174D–SEPTEMBER2003–REVISED Figure14.Bipolar Current Measurement Using Differential Input of A/D Converter10Submit Documentation Feedback Copyright©2003–2010,Texas Instruments Incorporated分销商库存信息:TIINA168QDBVRQ1INA168QPWRG4Q1。

AC measurements assume t T = 2ns.2. An initial pause of 100 is required after power up, and it followed by a minimum of eightinitialization cycles (RAS - only refresh cycle or CAS - before - RAS refresh cycle). If the internal refresh counter is used, a minimun of eight CAS - before - RAS refresh cycles are required.3. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device.4. All the V CC and V SS pins shall be supplied with the same voltages.5. t RAS (min) = t RWD (min)+t RWL (min)+t T in read-modify-write cycle.6. t CAS (min) = t CWD (min)+t CWL (min)+t T in read-modify-write cycle.7. t ASC (min), t RCS (min), t WCS (min), and t RPC are determined by the falling edge of CAS .8. t RCD (max) is specified as a reference point only, and t RAC (max) can be met with the t RCD (max) limit.Otherwise, t RAC is controlled exclusively by t CAC if t RCD is greater than the specified t RCD (max) limit. 9. t RAD (max) is specified as a reference point only, and t RAC (max) can be met with the t RAD (max) limit.Otherwise, t RAC is controlled exclusively by t AA if t RAD is greater than the specified t RAD (max) limit. 10. t CRP , t CHR , t RCH , t CPA and t CPW are determined by the rising edge of CAS .11. V IH (min) and V IL (max) are reference levels for measuring timing or input signals. Therefore, transitiontime is measured between V IH and V IL .12. Assumes that t RCD tRCD (max) and t RAD t RAD (max). If t RCD or t RAD is greater than the maximum recommended value shown in this table, t RAC exceeds the value shown. 13. Assumes that (max) and (max).14. Access time is determined by the maximum of t AA , t CAC , t CPA . 15. Assumes that (max) and (max). 16. Either t RCH or t RRH must be satisfied for a read cycle.17. t OFF (max) and t OEZ (max) define the time at which the output achieves the open circuit condition (highimpedance). t OFF is determined by the later rising edge of RAS or CAS.18. t WCS , t RWD , t CWD , and t AWD are not restrictive operating parameters. They are included in the datasheet as electrical characteristics only. If (min), the cycle is an early write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle. If (min),(min), (min) and (min), the cycle is a read-modify-write and the data output will contain data read from the selected cell. If neither of the above sets of conditions is satisfied, the condition of the data output (at access time) is indeterminate.19. These parameters are referenced to CAS separately in an early write cycle and to WE edge in adelayed write or a read-modify-write cycle.20. t RASP defines RAS pulse width in EDO page mode cycles.µs ≤≤t RCD t RCD ≥t RADt RAD ≤t RCD t RCD ≤t RAD t RAD ≥t WCS t WCS ≥t RWD t RWD ≥t CWDt CWD ≥t AWD t AWD ≥t CPW t CPW≥Timing Waveforms• Read Cyclet RC t RASt RPtCRPtCPNtRRHtRCHt OEZ t OFF tOEA tCACt AAtRACt CLZD OUTtRCS t ASR tRAH tASC tCAH tRAD t RALtCAStRSH tRCDt TtCSHRASCASADDRESSWEDQ1~DQ4Note : = don’t care OEt OFFRowColumn= Invalid Dout•Early Write CycletRC t RASt RPt WCHt DSt DHt WCS t RALtCAStRSH tRCDt TtCSHRASCASWEDQ1~DQ4tCRPtASRtRAH tASCtCAH ADDRESSColumnRowtCPND INtRADt RAL• Delayed Write CycletRC t RASt RPt RWL t RCSt CAStRSH tRCDt TtCSHRASCAStASR tRAH tCAHADDRESSColumnRow tASC D INDQ1~DQ4WEtCRPtCPNt DHt DSt OEHt OEDOEt DSOPENt WPt CWL• Read - Modify - Write CycletRWC t RASt RPtRWDt WPtRADtRWL tCAStCWL tRCDt TtCPNRASCASWEtCRP t ASRtRAHtASCtCAHADDRESS Column RowDQ1~DQ4t DHt DSOEtRCStAWD tCWD D INt OEDt OEHt OEZt OEA t CAC t RACt AADQ1~DQ4D OUTOPENtDZCtDZO• EDO Page Mode Read CycletRASPtCPRHt RCStCAStRSH tRCDt OEAtCSHRASCAStASRtRAHtCAHADDRESStCASWEtCRPt CPOEDQ1~DQ4OPENtOEPD OUT 1t PCt CPtCAStCPNtCRPtRADtCAHtASCt ASCtCAHt ASCt RAL Row Column 1t OEAt OEHCtRRH tRCHt RACt AAt AAt AA t CPA t CPA t OEZt OFFt OFFt CACt OEZt CAC t CACt COHD OUT NWE OE Column 2Column N Rowt RPD OUT 2• EDO Page Mode Early Write CycletRASPtRPt WCSt CAStRSH tRCDRASCAStASRtRAHtCAHADDRESStCASWEt CPDQ1~DQ4t PCt CPt CAStCPNtCRP tCAH tASCtASC tCAH tASC Row Column 1t DS WE Column 2Column Nt WCH t WCS t WCH t WCS t WCHt DH t DS t DH t DS t DHD IN 1D IN 2D IN Nt TtCSH• EDO Page Mode Read-Early-Write Cyclet RASPtCPRHt RCStCAStRSH tRCDt OEAtCSHRASCAStASRtRAHtCAHADDRESStCASWEtCRPt CPOEDQ1~DQ4OPENtWEDt PCt CPtCAStCPNtCRPtRADtRAHtASCt ASCtCAHt ASCt RAL Row Column 1tWCStRCHt RACt AAt AAt CPA t DHt WHZt CACt CACt COHWE OE Column 2Column N Rowt RPt CAL tWCHDataDoutput 2Data Input NDataDoutput 1t DStCSH• EDO Page Mode Read-Modify-Write Cyclet RASPt CPRHt RCStCASt WP RASCASt ASRtRAHtCAHADDRESSt CASWEtRCDCPDQ1~DQ4tPRWCt CPtCAStCRPtRADtCAHtASCt ASCtCAH tASC Row Column 1tRWLtRCSt OEDt DZOt CAC WE OEt RPt RAL D OUT 2D OUT ND OUT 1tTt Column NColumn 2Column 1tRWD tAWD tCWDtCWLtRCStCWDtAWD tCPW tCWL tCPW tAWD tCWDtCWL t OEDt OEDt OEHt OEHt OEHt CAC t CAC t OEA t AAt RACt OEZt OEAt AA t CPAt OEZt OEAt AA t CPAt OEZ t DSt DHt WP t DSt DHt WP t DSt DHOPENOPENOPEN D IN 1D IN ND IN 2DQ1~DQ4t DZCt DZOt DZCt DZCt DZO• Read Cycle with WE Controlled Disablet WPZt RCStCAStRCDt TtCSHRASCASt ASRtRAHtCAHADDRESSColumnRow tASCD DQ1~DQ4WEt OEZt DSt WHZOEt RCH t OEA t CACt AAt RACt CLZOUTtRADRASADDRESSt RC t CRPt ASRt RAHt Tt RPCROWt OFFCAS t RASt RPOPENt CRPDQ1~DQ4RASt CSRt WSRt RPt T t RPCt OFFCAS t RASt RPOPENt CRPDQ1~DQ4t RPCt CHRt RASt RPt RCt RCt CHRt CSRt WHRt WSRt WHRWECAS-Before-RAS Refresh CycleRASWEt RPCt OFFt CSRt CHSt WSRCASt RASS t RPSOPENDQ1~DQ4t WHRHigh lmpedance• Hidden Refresh Cyclet RPt RASRASt RCDt CRPADDRESSWEt CHRt CASt RSHt RAHt ASRt ASCt CAHt RAL ROW t RCHt OEZCASDQ1~DQ4t Tt RCSD t RASt RASt RPt RPt RC t RCt RCt RADt RRHt OFF t OFFt OEA t CACt AAt RACCOlumnOUTOE(READ)(REFRESH)(REFRESH)Ordering informationAD404M42VSA-5• AD• Ascend Memory Product • 40 • Device Type• 4M4 • Density and Organization • 2• Refresh Rate, 2: 2K Refresh • V• T: 5V, V: 3.3V• S • Package Type (S : SOJ, T : TSOP II)• A• Version• 5• Speed (5: 50 ns, 6: 60 ns)Part Number Access time PackageAD404M42VSA-5AD404M42VSA-6AD404M42VTA-5AD404M42VTA-650 ns 60 ns 50 ns 60 ns300mil 26/24-Pin Plastic SOJTSOP IIPackaging information • 300 mil, 26/24-Pin Plastic SOJ• 300 mil, 26/24-Pin TSOP II。

AD420中文资料摘要:AD420是具有灵活串行数字接口的16住数模转换器,它带有SPI和Microwire总线接口,使用方便、性价比高。
介绍了AD420的引脚功能、电气特性,阐述了AD420与MSP430的接口技术,并给出了在MSP430控制下的实际应用电路及程序。
关键词:AD420;D/A转换;MSP430;电流环1 概述AD420是ADI公司生产的高精度、低功耗全数字电流环输出转换器。
AD420的输出信号可以是电流信号,也可以是电压信号。
其中电流信号的输出范围为4mA~20mA,0mA~20mA或0mA~24mA,具体可通过引脚RANGE SELECTl,RANGE SELECT2进行配置。
当需要输出电压信号时,它也能从一个隔离引脚提供电压输出,这时需外接一个缓冲放大器,可输出0V~5V,0V~10V,±5V 或±10V电压。
AD420具有灵活的串行数字接口(最大速率可达3.3 Mb/s),使用方便、性价比高、抑制干扰能力强,非常适合用于高精度远程控制系统。
AD420与单片机的接口方式有2种:3线制和异步制。
单片机系统通过AD420可实现连续的模拟量输出。
其主要特点如下:宽泛的电源电压范围为12 V~32 V,输出电压范围为0V~-2.5 V;带有3线模式的SPI或Microwire接口,可采集连续的模拟输入信号,采用异步模式时仅需少量的信号线;数据输出引脚可将多个AD420器件连接成菊链型;上电初始化时,其输出最小值为0 mA,4 mA或O V;具有异步清零引脚,可将输出复位至最小值(0mA、4 mA或0V);BOOST引脚可连接一个外部晶体管来吸收回路电流,降低功耗;只需外接少量的外部器件,就能达到较高的精度。
AD420采用24引脚SOIC和PDIP封装,表1是其引脚功能说明。
2 工作原理在AD420中,二阶调节器用于保持最小死区。
从调节器发出的单字节流控制开关电流源,两个连续的电阻电容装置进行过滤。

AC measurements assume t T = 2ns.2. An initial pause of 100 is required after power up, and it followed by a minimum of eightinitialization cycles (RAS - only refresh cycle or CAS - before - RAS refresh cycle). If the internal refresh counter is used, a minimun of eight CAS - before - RAS refresh cycles are required.3. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device.4. All the V CC and V SS pins shall be supplied with the same voltages.5. t RAS (min) = t RWD (min)+t RWL (min)+t T in read-modify-write cycle.6. t CAS (min) = t CWD (min)+t CWL (min)+t T in read-modify-write cycle.7. t ASC (min), t RCS (min), t WCS (min), and t RPC are determined by the falling edge of CAS .8. t RCD (max) is specified as a reference point only, and t RAC (max) can be met with the t RCD (max) limit.Otherwise, t RAC is controlled exclusively by t CAC if t RCD is greater than the specified t RCD (max) limit. 9. t RAD (max) is specified as a reference point only, and t RAC (max) can be met with the t RAD (max) limit.Otherwise, t RAC is controlled exclusively by t AA if t RAD is greater than the specified t RAD (max) limit. 10. t CRP , t CHR , t RCH , t CPA and t CPW are determined by the rising edge of CAS .11. V IH (min) and V IL (max) are reference levels for measuring timing or input signals. Therefore, transitiontime is measured between V IH and V IL .12. Assumes that t RCD tRCD (max) and t RAD t RAD (max). If t RCD or t RAD is greater than the maximum recommended value shown in this table, t RAC exceeds the value shown. 13. Assumes that (max) and (max).14. Access time is determined by the maximum of t AA , t CAC , t CPA . 15. Assumes that (max) and (max). 16. Either t RCH or t RRH must be satisfied for a read cycle.17. t OFF (max) and t OEZ (max) define the time at which the output achieves the open circuit condition (highimpedance). t OFF is determined by the later rising edge of RAS or CAS.18. t WCS , t RWD , t CWD , and t AWD are not restrictive operating parameters. They are included in the datasheet as electrical characteristics only. If (min), the cycle is an early write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle. If (min),(min), (min) and (min), the cycle is a read-modify-write and the data output will contain data read from the selected cell. If neither of the above sets of conditions is satisfied, the condition of the data output (at access time) is indeterminate.19. These parameters are referenced to CAS separately in an early write cycle and to WE edge in adelayed write or a read-modify-write cycle.20. t RASP defines RAS pulse width in EDO page mode cycles.µs ≤≤t RCD t RCD ≥t RADt RAD ≤t RCD t RCD ≤t RAD t RAD ≥t WCS t WCS ≥t RWD t RWD ≥t CWDt CWD ≥t AWD t AWD ≥t CPW t CPW≥Timing Waveforms• Read Cyclet RC t RASt RPtCRPtCPNtRRHtRCHt OEZ t OFF tOEA tCACt AAtRACt CLZD OUTtRCS t ASR tRAH tASC tCAH tRAD t RALtCAStRSH tRCDt TtCSHRASCASADDRESSWEDQ1~DQ4Note : = don’t care OEt OFFRowColumn= Invalid Dout•Early Write CycletRC t RASt RPt WCHt DSt DHt WCS t RALtCAStRSH tRCDt TtCSHRASCASWEDQ1~DQ4tCRPtASRtRAH tASCtCAH ADDRESSColumnRowtCPND INtRADt RAL• Delayed Write CycletRC t RASt RPt RWL t RCSt CAStRSH tRCDt TtCSHRASCAStASR tRAH tCAHADDRESSColumnRow tASC D INDQ1~DQ4WEtCRPtCPNt DHt DSt OEHt OEDOEt DSOPENt WPt CWL• Read - Modify - Write CycletRWC t RASt RPtRWDt WPtRADtRWL tCAStCWL tRCDt TtCPNRASCASWEtCRP t ASRtRAHtASCtCAHADDRESS Column RowDQ1~DQ4t DHt DSOEtRCStAWD tCWD D INt OEDt OEHt OEZt OEA t CAC t RACt AADQ1~DQ4D OUTOPENtDZCtDZO• EDO Page Mode Read CycletRASPtCPRHt RCStCAStRSH tRCDt OEAtCSHRASCAStASRtRAHtCAHADDRESStCASWEtCRPt CPOEDQ1~DQ4OPENtOEPD OUT 1t PCt CPtCAStCPNtCRPtRADtCAHtASCt ASCtCAHt ASCt RAL Row Column 1t OEAt OEHCtRRH tRCHt RACt AAt AAt AA t CPA t CPA t OEZt OFFt OFFt CACt OEZt CAC t CACt COHD OUT NWE OE Column 2Column N Rowt RPD OUT 2• EDO Page Mode Early Write CycletRASPtRPt WCSt CAStRSH tRCDRASCAStASRtRAHtCAHADDRESStCASWEt CPDQ1~DQ4t PCt CPt CAStCPNtCRP tCAH tASCtASC tCAH tASC Row Column 1t DS WE Column 2Column Nt WCH t WCS t WCH t WCS t WCHt DH t DS t DH t DS t DHD IN 1D IN 2D IN Nt TtCSH• EDO Page Mode Read-Early-Write Cyclet RASPtCPRHt RCStCAStRSH tRCDt OEAtCSHRASCAStASRtRAHtCAHADDRESStCASWEtCRPt CPOEDQ1~DQ4OPENtWEDt PCt CPtCAStCPNtCRPtRADtRAHtASCt ASCtCAHt ASCt RAL Row Column 1tWCStRCHt RACt AAt AAt CPA t DHt WHZt CACt CACt COHWE OE Column 2Column N Rowt RPt CAL tWCHDataDoutput 2Data Input NDataDoutput 1t DStCSH• EDO Page Mode Read-Modify-Write Cyclet RASPt CPRHt RCStCASt WP RASCASt ASRtRAHtCAHADDRESSt CASWEtRCDCPDQ1~DQ4tPRWCt CPtCAStCRPtRADtCAHtASCt ASCtCAH tASC Row Column 1tRWLtRCSt OEDt DZOt CAC WE OEt RPt RAL D OUT 2D OUT ND OUT 1tTt Column NColumn 2Column 1tRWD tAWD tCWDtCWLtRCStCWDtAWD tCPW tCWL tCPW tAWD tCWDtCWL t OEDt OEDt OEHt OEHt OEHt CAC t CAC t OEA t AAt RACt OEZt OEAt AA t CPAt OEZt OEAt AA t CPAt OEZ t DSt DHt WP t DSt DHt WP t DSt DHOPENOPENOPEN D IN 1D IN ND IN 2DQ1~DQ4t DZCt DZOt DZCt DZCt DZO• Read Cycle with WE Controlled Disablet WPZt RCStCAStRCDt TtCSHRASCASt ASRtRAHtCAHADDRESSColumnRow tASCD DQ1~DQ4WEt OEZt DSt WHZOEt RCH t OEA t CACt AAt RACt CLZOUTtRADRASADDRESSt RC t CRPt ASRt RAHt Tt RPCROWt OFFCAS t RASt RPOPENt CRPDQ1~DQ4RASt CSRt WSRt RPt T t RPCt OFFCAS t RASt RPOPENt CRPDQ1~DQ4t RPCt CHRt RASt RPt RCt RCt CHRt CSRt WHRt WSRt WHRWECAS-Before-RAS Refresh CycleRASWEt RPCt OFFt CSRt CHSt WSRCASt RASS t RPSOPENDQ1~DQ4t WHRHigh lmpedance• Hidden Refresh Cyclet RPt RASRASt RCDt CRPADDRESSWEt CHRt CASt RSHt RAHt ASRt ASCt CAHt RAL ROW t RCHt OEZCASDQ1~DQ4t Tt RCSD t RASt RASt RPt RPt RC t RCt RCt RADt RRHt OFF t OFFt OEA t CACt AAt RACCOlumnOUTOE(READ)(REFRESH)(REFRESH)Ordering informationAD404M42VSA-5• AD• Ascend Memory Product • 40 • Device Type• 4M4 • Density and Organization • 2• Refresh Rate, 2: 2K Refresh • V• T: 5V, V: 3.3V• S • Package Type (S : SOJ, T : TSOP II)• A• Version• 5• Speed (5: 50 ns, 6: 60 ns)Part Number Access time PackageAD404M42VSA-5AD404M42VSA-6AD404M42VTA-5AD404M42VTA-650 ns 60 ns 50 ns 60 ns300mil 26/24-Pin Plastic SOJTSOP IIPackaging information • 300 mil, 26/24-Pin Plastic SOJ• 300 mil, 26/24-Pin TSOP II。
