NOTES:
1. A write occurs during the overlap of a LOW CS and a LOW WE .
2. t WR is measured from the earlier of CS or WE going HIGH to the end of the write cycle.
3. During this period, I/O pins are in the output state so that the input signals must not be applied.
4. If the CS LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high-impedance state.
5. Transition is measured ±200mV from steady state.
6. If OE is LOW during a WE controlled write cycle, the write pulse width must be the larger of t WP or (t WHZ + 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 a WE controlled write cycle, this requirement does not apply and the write pulse can be as short as the
spectified t WP.

NOTES:
1. WE or CS must be HIGH during all address transitions.
2. A write occurs during the overlap of a LOW CS and a LOW WE .
3. t WR is measured from the earlier of CS or WE going HIGH to the end of the write cycle.
4. If the CS LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high-impedance state.
5. If OE is LOW during a WE controlled write cycle, the write pulse width must be the larger of t WP or (t WHZ + 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 a WE controlled write cycle, this requirement does not apply and the write pulse can be as short as the
