ABSOLUTE MAXIMUM RATINGS
Note a: Stresses greater than those listed under “Absolute Maximum Rat-
ings” 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 d: E ≥2VIH 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.
