M69KB096AA

Note: 1. WE# LOW time must be limited to tCEM (8 µs).

2. These timings have been obtained with the AC Measurement Load Circuit shown on Figure 14. The transition timings measure a

transition of 100 mV between the High-Z level (VCCQ/2) and VOH or VOL.

3. These timings have been obtained with the AC Measurement Load Circuit shown on Figure 14. The High-Z timings measure a tran-

sition of 100 mV between VOH or VOL and VCCQ/2.

Note: 1. Non default BCR Register settings: Latency code two (three clocks); WAIT active Low; WAIT asserted during delay.

2. Clock rates lower than 50MHz (clock period higher than 20ns) are allowed as long as tELKH specifications are met.
