Brown-out Detection
48
ATmega162(V/U/L)
ATmega162 has an On-chip Brown-out Detection (BOD) circuit for monitoring the V
level during operation by comparing it to a fixed trigger level. The trigger level for the
BOD can be selected by the BODLEVEL Fuses. The trigger level has a hysteresis to
ensure spike free Brown-out Detection. The hysteresis on the detection level should be
interpreted as V

Notes:

When the BOD is enabled and V

devices where this is the case, the device is tested down to V
production test. This guarantees that a Brown-out Reset will occour before V
to a voltage where correct operation of the microcontroller is no longer guarateed.
This test is performed using BODLEVEL = 110 for ATmega162V, BODLEVEL = 101
for ATmega162L, and BODLEVEL = 100 for ATmega162.
