All
dsPIC33FJ32(GP/MC)101/102/104 devices power
their core digital logic at a nominal 2.5V. This can
create a conflict for designs that are required to operate
at a higher typical voltage, such as 3.3V. To simplify
system design, all devices in the dsPIC33FJ16(GP/
MC)101/102 and dsPIC33FJ32(GP/MC)101/102/104
family incorporate an on-chip regulator that allows the
device to run its core logic from V

The Brown-out Reset (BOR) module is based on an
internal voltage reference circuit that monitors the
regulated supply voltage, V
the BOR module is to generate a device Reset when a
brown-out condition occurs. Brown-out conditions are
generally caused by glitches on the AC mains (for
example, missing portions of the AC cycle waveform
due to bad power transmission lines or voltage sags
due to excessive current draw when a large inductive
load is turned on).
A BOR generates a Reset pulse, which resets the
device. The BOR selects the clock source, based on
the device Configuration bit values (FNOSC<2:0> and
POSCMD<1:0>).
If an Oscillator mode is selected, the BOR activates the
Oscillator Start-up Timer (OST). The system clock is
held until OST expires. If the PLL is used, the clock is
held until the LOCK bit (OSCCON<5>) is ‘1’.
Concurrently, the PWRT Time-out (T
