PIC32MX3XX/4XX

All PIC32MX3XX/4XX device’s core and digital logic
are designed to operate at a nominal 1.8V. To simplify
system
PIC32MX3XX/4XX incorporate an on-chip regulator
providing the required core logic voltage from V
The internal 1.8V regulator is controlled by the
ENVREG pin. Tying this pin to V

ESR capacitor (such as tantalum) must be connected
to the V

mended value for the filer capacitor is provided in

When the voltage regulator is enabled, it takes fixed
delay for it to generate output. During this time, desig-

PIC32MX3XX/4XX 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 specific in
