24.2
All of the PIC24FJ64GA004 family of devices power
their core digital logic at a nominal 2.5V. This may
create an issue for designs that are required to operate
at a higher typical voltage, such as 3.3V. To simplify
system design, all devices in the PIC24FJ64GA004
family incorporate an on-chip regulator that allows the
device to run its core logic from V
The regulator is controlled by the DISVREG pin. Tying
V
vides power to the core from the other V
the regulator is enabled, a low-ESR capacitor (such as
ceramic) must be connected to the V
(Figure 24-1). This helps to maintain the stability of the
regulator. The recommended value for the filter capacitor
is provided in Section 27.1 “DC Characteristics”.
If DISVREG is tied to V
this case, separate power for the core logic at a nomi-
nal 2.5V must be supplied to the device on the
V
levels, typically 3.3V. Alternatively, the V
and V
nominal voltage. Refer to Figure 24-1 for possible
configurations.
24.2.1
When it is enabled, the on-chip regulator provides a
constant voltage of 2.5V nominal to the digital core
logic.
The regulator can provide this level from a V
2.5V, all the way up to the device’s V
have the capability to boost V
order to prevent “brown out” conditions when the volt-
age drops too low for the regulator, the regulator enters
Tracking mode. In Tracking mode, the regulator output
follows V
When the device enters Tracking mode, it is no longer
possible to operate at full speed. To provide information
about when the device enters Tracking mode, the
on-chip regulator includes a simple, Low-Voltage
Detect circuit. When V
ating voltage, the circuit sets the Low-Voltage Detect
Interrupt Flag, LVDIF (IFS4<8>). This can be used to
generate an interrupt and put the application into a
low-power operational mode, or trigger an orderly
shutdown.
Low-Voltage Detection is only available when the
regulator is enabled.

If the regulator is disabled, a separate Power-up Timer
