PIC24FJ64GA104 FAMILY
25.2
All PIC24FJ64GA104 family 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 PIC24FJ64GA104 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
to the pin enables the regulator, which in turn, provides
power to the core from the other V

When it is enabled, the on-chip regulator provides a
constant voltage of 2.5V nominal to the digital core

Tracking mode. In Tracking mode, the regulator output

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

Interrupt Flag, LVDIF (IFS4<8>). This can be used to

shutdown.
Low-Voltage Detection is only available when the
regulator is enabled.
