Notes: 1. tAS is measured from the address valid to the beginning of Write.

2. A Write occurs during the overlap (tWP) of a low CE and a low WE .

3. tWR is measured from the earliest of CE or WE going high to the end of the Write cycle

4. If the CE low transition occurs simultaneously with the WE low transition or after the WE transition, outputs

remain in a high impedance state.

5. tCW is measured from the later of CE going low to the end of Write.

6. OE is continuously low. ( OE = VIL)

7. Transition is measured ±200mV from steady state. This parameter is sampled and not 100% tested.
