This parameter is sampled, but not 100% tested.

3

For test conditions, see AC Test Conditions, Figures A, B, and C.

5

This parameter is guaranteed, but not 100% tested.

6WE is High for read cycle.

7CE and OE are Low for read cycle.

8

Address valid prior to or coincident with CE transition Low.

9

All read cycle timings are referenced from the last valid address to the first transitioning address.

10 CE or WE must be High during address transitions. Either CE or WE asserting high terminates a write cycle.

11 All write cycle timings are referenced from the last valid address to the first transitioning address.

12 Not applicable.

13 2V data retention applies to the commercial operating range only.

14 C=30pF, except on High Z and Low Z parameters, where C=5pF.
