Write Cycle No. 2: CE Controlled Timing
Write Cycle No. 1: R/W Controlled Timing
Notes:
24. R/W must be HIGH during all address transitions.
25. A write occurs during the overlap (t
26. t
27. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of t
28. To access RAM, CE = V
29. 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.
30. During this period, the I/O pins are in the output state, and input signals must not be applied.
31. 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.
