System and Reset Characteristics
Notes: 1. Values are guidelines only.
2. The Power-on Reset will not work unless the supply voltage has been below V
POT
(falling)
Notes: 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 guarantees that a Brown-Out Reset will occur before V
CC
drops to a voltage where correct operation of the microcontroller is no longer guaranteed. The test is performed using
BODLEVEL = 110, 101 and 100.
BODLEVEL = 110, 101 and 100.
