All
PIC24HJ16GP304 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
PIC24HJ16GP304 family incorporate an on-chip regu-
lator that allows the device to run its core logic from

out condition occurs. Brown-out conditions are gener-
ally 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 exces-
sive 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) will be
applied before the internal Reset is released. If TPWRT
= 0 and a crystal oscillator is being used, 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. If the BOR circuit is enabled, it
continues to operate while in Sleep or Idle mode and
resets the device in case VDD falls below the BOR
threshold voltage.
