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 a LOW CE and a LOW R/ W for memory array writing cycle.
3. t WR is measured from the earlier of CE or R/ W (or SEM or R/ W ) going HIGH 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 or SEM 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 is asserted last, CE or R/ W .
7. This parameter is guaranteed by 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 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 and data to be placed
on the bus for the required t DW . 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
t WP .
9. To access RAM, CE = V I L and SEM = V I H . To access semaphore , CE = V IH and SEM = V IL . t EW must be met for either condition.
