29.4 System and Reset Characterizations
Notes: 1. Values are guidelines only.
2. This is the limit to which VDD can be lowered without losing RAM data
Note:
1. V
BOT
may be below nominal minimum operating voltage for some devices. For devices where
this is the case, the device is tested down to V
CC
= V
BOT
during the production test. This guar-
antees that a Brown-out Reset will occur before V
CC
drops to a voltage where correct
operation of the microcontroller is no longer guaranteed.
