ADDRESS
Timing Waveform of Write Cycle No. 1, (R/W Controlled Timing)
Timing Waveform of Write Cycle No. 2, (CE Controlled Timing)
NOTES:
1. R/W or CE must be HIGH during all address transitions.
2. A write occurs during the overlap (t
3. t
4. During this period, the l/O pins are in the output state and input signals must not be applied.
5. If the CE LOW transition occurs simultaneously with or after the R/W LOW transition, the outputs remain in the HIGH impedance state.
6. Timing depends on which enable signal (CE or R/W) is asserted last.
7. This parameter is determined by device characterization, but is not production tested. Transition is measured 0mV from steady state with the Output Test Load
8. If OE is LOW during a R/W controlled write cycle, the write pulse width must be the larger of t
