The specified values are obtained with outputs unloaded. Note c: ICC 2 and ICC 4 are the average currents required for the duration of the respective STORE cycles (tSTORE ). Note d: E ≥ V IH will not produce standby current levels until any nonvolatile cycle in progress has timed out. AC TEST CONDITIONS CAPACITANCEe (T A = 25 °C, f = 1.0MHz) Note e: These parameters are guaranteed but not tested.

This is a stress rating only, and functional operation of the device at condi- tions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rat- ing conditions for extended periods may affect reliability. |
