ENDURANCE AND DATA RETENTION
CAPACITANCE
POWER-UP TIMING
POWER UP AND DOWN REQUIREMENTS
The are no restrictions on the power-up or power-down conditions of V
CC
and the voltages applied to the poten-
tiometer pins provided that V
CC
is always more positive than or equal to V
H
, V
L
, and V
W
, i.e., V
CC
≥
V
H
, V
L
, V
W
. The
V
CC
power-up timing spec is always in effect.
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.
