NOTES:
1. R/ W or CE or UB & LB = V IH during all address transitions.
2. A write occurs during the overlap (t EW or t WP ) of a UB or LB = V IL and a CE = V IL and a R/ W = V IL 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 = V IL 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 = V IL 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 , R/ W , UB , or LB .
7. This parameter is guaranted by device characterization, but is not production tested. Transition is measured 0mV steady state with the Output Test Load
(Figure 2).
8. If OE = V IL during R/ W controlled write cycle, the write pulse width must be the larger of t WP for (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 = 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 .
9. To access RAM, CE = V IL , UB or LB = V IL , and SEM = V IH . To access Semaphore, CE = V IH or UB & LB = V IH , and SEM = V IL . t EW must be
met for either condition.
