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.
DC CHARACTERISTICS
(VCC = 3 - 3.6V)
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:
CC2 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 VCC if that is where the power supply connection is made, or VCAP if VCC is connected to
ground.
