PIC32MX5XX/6XX/7XX
28.3
All PIC32MX5XX/6XX/7XX devices’ core and digital
logic are designed to operate at a nominal 1.8V. To
simplify system designs, most devices in the
PIC32MX5XX/6XX/7XX family incorporate an on-chip
regulator providing the required core logic voltage from
V
A low-ESR capacitor (such as tantalum) must be
connected to the V
This helps to maintain the stability of the regulator.
The recommended value for the filter capacitor is
provided in
28.3.1
It takes a fixed delay for the on-chip regulator to generate
an output. During this time, designated as T
execution is disabled. T
device resumes operation after any power-down,
including Sleep mode.
28.3.2
PIC32MX5XX/6XX/7XX devices also have a simple
brown-out capability. If the voltage supplied to the
regulator is inadequate to maintain a regulated level,
the regulator Reset circuitry will generate a Brown-out
Reset. This event is captured by the BOR flag bit
(RCON<1>). The brown-out voltage levels are
specified in

The on-chip regulator is designed to meet the power-up
requirements for the device. If the application does not
use the regulator, strict power-up conditions must be
adhered to. While powering up, V
