NOTES:
1. R/ W or CE must be HIGH during all address transitions.
2. A write occurs during the overlap (t EW or t WP ) of CE = V IL and R/W= V IL .
3. t WR is measured from the earlier of CE or R/ W going HIGH to the end of the write cycle.
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 to be device characterization, but is not production tested. Transition is measured 0mV from steady state with the Output Test
Load (Figure 2).
8. If OE is LOW 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 is HIGH during a R/ W controlled write cycle, this requirement does not apply and the write pulse can be as short
as the specified t WP .
