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 conditions above

those indicated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions for extended

periods may affect reliability.

Note b: ICC is dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded.

Note c: Bringing E

≥ VIH will not produce standby current levels until any nonvolatile cycle in progress has timed out. See MODE SELECTION table.

Note d: ICC is the average current required for the duration of the store cycle (tSTORE) after the sequence (tWC) that initiates the cycle.
