PIC24FJ256DA210 FAMILY
REGISTER 27-6:
27.2
All PIC24FJ256DA210 family devices power their core
digital logic at a nominal 1.8V. 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 PIC24FJ256DA210 family
incorporate an on-chip regulator that allows the device
to run its core logic from V
The regulator is controlled by the ENVREG pin. Tying V
to the pin enables the regulator, which in turn, provides
power to the core from the other V
ulator is enabled, a low-ESR capacitor (such as ceramic)
must be connected to the V

mended value for the filter capacitor (C

27.2.1
When the on-chip regulator is enabled, it provides a
constant voltage of 1.8V nominal to the digital core
logic.
The regulator can provide this level from a V

vent “brown-out” conditions when the voltage drops too
low for the regulator, the Brown-out Reset occurs. Then
the regulator output follows V
drop of 300 mV.
To provide information about when the regulator
voltage starts reducing, the on-chip regulator includes
a simple Low-Voltage Detect circuit, which sets the
