Power Requirements
All devices in the PIC32MX family are dual voltage
supply designs: one supply for the core and peripherals
and another for the I/O pins. Some devices contain an
on-chip regulator to eliminate the need for two external
voltage supplies.
All of the PIC32MX 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 PIC32MX family incorporate an on-chip
regulator that allows the device to run its core logic from
VDD.
The regulator provides power to the core from the other
VDD pins. A low-ESR capacitor (e.g., a tantalum
capacitor) must be connected to the VCAP pin
(Figure 4-2). This helps to maintain the stability of the
regulator. The specifications for core voltage and
capacitance
are
listed
