Preliminary

Table 15: Asynchronous WRITE Cycle Timing Requirements

Note:

1. The High-Z timings measure a 100mV transition from either VOH or VOL toward VccQ/2.

2. The Low-Z timings measure a 100mV transition away from the High-Z (VccQ/2) level toward either VOH or VOL.

3. WE# Low time must be limited to tCEM (4µs).
