DC CHARACTERISTICS(VCC = 3.0V +20%, -10%)e

Note b: ICC

and ICC

are dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded.

Note c: ICC

and ICC

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.
