The
dsPIC33FJ16MC304 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
dsPIC33FJ16MC304 family incorporate an on-chip
regulator that allows the device to run its core logic from

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.
