Note a: Stresses greater than those listed under “Absolute Maximum Rat-
ings” may cause permanent damage to the device. This is a stress
rating only, and functional operation of the device at conditions
above those indicated in the operational sections of this specifica-
tion is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect reliability.
DC CHARACTERISTICS
(VCC = 3.0V-3.6V)
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.
