All
dsPIC33FJ64GPX02/X04, and dsPIC33FJ128GPX02/
X04 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
dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/X04,
and dsPIC33FJ128GPX02/X04 family incorporate an
on-chip regulator that allows the device to run its core
logic from V
The regulator provides power to the core from the other

The Brown-out Reset (BOR) module is based on an
internal voltage reference circuit that monitors the reg-
ulated supply voltage V
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 (TPWRT) is applied
before the internal Reset is released. If TPWRT = 0 and
a crystal oscillator is being used, then a nominal delay
of TFSCM = 100 is applied. The total delay in this case
is TFSCM.
The BOR Status bit (RCON<1>) is set to indicate that a
BOR has occurred. The BOR circuit continues to oper-
ate while in Sleep or Idle modes and resets the device
should VDD fall below the BOR threshold voltage.
