Notes

1. X means "Don

2. ZZ pin is pulled down internally

3. For write cycles that following read cycles, the output buffers must be

disabled with OE, otherwise data bus contention will occur.

4. Sleep Mode means power down state of which stand-by current does

not depend on cycle time.

5. Deselected means power down state of which stand-by current

depends on cycle time.
