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 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.

The STK11C88-20 requires VCC = 5.0V ± 5% supply to operate at specified speed.
ICC1 and ICC3 are dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded.
ICC is the average current required for the duration of the STORE cycle (tSTORE ) .
E ≥2VIH will not produce standby current levels until any nonvolatile cycle in progress has timed out.
