= –20 to +70 C, V

2.
Refers to the voltage with which the POC circuit cancels an internal reset. If V
POC
< V
DD
, the internal
reset is released.
From the time of V

DD
until the internal reset takes effect, lag of up to 1 ms occurs. When the
period of V

lasts less than 1 ms, the internal reset may not take effect.
