All PIC32MX5XX/6XX/7XX device’s core and digital
logic are designed to operate at a nominal 1.8V. To sim-

ommended value for the filer capacitor is provided in
Section 31.1 “DC Characteristics” .
28.3.1
It takes a fixed delay for the on-chip regulator to generate
output. During this time, designated as T
tion is disabled. T
resumes operation after any power-down, including
Sleep mode.
If the regulator is disabled, a separate Power-up Timer
(PWRT) is automatically enabled. The PWRT adds a
fixed delay of T

information on T
28.3.2
PIC32MX5XX/6XX/7XX devices also have a simple
brown-out capability. If the voltage supplied to the reg-
ulator 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 specific
in Section 31.1 “DC Characteristics” .

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