ENDURANCE AND DATA RETENTION
CAPACITANCE
POWER-UP TIMING
A.C. TEST CONDITIONS
Notes:
(6) This parameter is not 100% tested
(7) t
PUR
and t
PUW
are the delays required from the time the (last) power supply (V
CC
-) is stable until the specific instruction can be
issued. These parameters are periodically sampled and not 100% tested.
