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. ABSOLUTE MAXIMUM RATINGSa DC CHARACTERISTICS (VCC = 5.0V ± 10%) e Note b: ICC 1 and ICC3 are dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded. Note c: ICC 2 and ICC4 are the average currents required for the duration of the respective STORE cycles (tSTORE ) . Note d: E ≥ V IH 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 if that is where the power supply connection is made, or VCAP if VCCX is connected to ground.
