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 STK25C48-20 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 and ICC are the average currents required for the duration of the respective STORE cycles (tSTORE ) .
E ≥2VIH will n4ot produce standby current levels until any nonvolatile cycle in progress has timed out.
