Write Cycle No. 2: CE Controlled Timing [21, 22, 23, 28] Switching Waveforms (continued) tAW tWC tPWE tHD tSD tHA CE R/W OE DATAOUT DATA IN ADDRESS tHZOE tSA tHZWE tLZWE [26] [26] [24] [25] NOTE 27 NOTE 27 tAW tWC tSCE tHD tSD tHA CE R/W DATA IN ADDRESS tSA [25] Notes 21. R/W or CE must be HIGH during all address transitions. 22. A write occurs during the overlap (tSCE or tPWE) of a LOW CE or SEM. 23. tHA is measured from the earlier of CE or R/W or (SEM or R/W) going HIGH at the end of write cycle. 24. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of tPWE or (tHZWE + tSD) to allow the I/O drivers to turn off and data to be placed on the bus for the required tSD. If OE is HIGH during an R/W controlled write cycle, this requirement does not apply and the write pulse can be as short as the specified tPWE. 25. To access RAM, CE = VIL, SEM = VIH. 26. Transition is measured ±500 mV from steady state with a 5-pF load (including scope and jig). This parameter is sampled and not 100% tested. 27. During this period, the I/O pins are in the output state, and input signals must not be applied. 28. If the CE or SEM LOW transition occurs simultaneously with or after the R/W LOW transition, the outputs remain in the high-impedance state. |
