NOTES:
1. R/ W or CE = V IH during all address transitions.
2. A write occurs during the overlap (t EW or t WP ) of a CE = V IL and a R/ W = V IL .
3. t WR is measured from the earlier of CE or R/ W = V IH to the end of write cycle.
4. During this period, the I/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 = V IL transition, the outputs remain in the High-impedance state.
6. Timing depends on which enable signal is asserted last, CE or R/ W .
7. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). This parameter is guaranteed but is not production tested.
8. If OE = V IL during a R/ W controlled write cycle, the write pulse width must be the larger of t WP or (t WZ + t DW ) to allow the I/O drivers to turn off data to be placed
on the bus for the required t DW . If OE = V IH during an R/ W controlled write cycle, this requirement does not apply and the write pulse can be as short as the
specified t WP .
