DC CHARACTERISTICS(VCC = 3.0V +20%, -10%)e
Note b: ICC
1
and ICC
3
are dependent on output loading and cycle rate. 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
≥ VIH will not produce standby current levels until any nonvolatile cycle in progress has timed out.
Note e: VCC reference levels throughout this datasheet refer to VCCX.

Note a: Stresses greater than those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. This is a
stress rating only, and functional operation of the device at con-
ditions 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.
