26.3
All PIC32MX1XX/2XX devices’ core and digital logic
are designed to operate at a nominal 1.8V. To simplify
system
PIC32MX1XX/2XX family incorporate an on-chip regu-
lator providing the required core logic voltage from
V
A low-ESR capacitor (such as tantalum) must be
connected to the V
helps to maintain the stability of the regulator. The
recommended value for the filter capacitor is provided
in
26.3.1
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.
26.3.2
PIC32MX1XX/2XX 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

PIC32MX1XX/2XX devices provide a complete range
of programming and diagnostic features that can
increase the flexibility of any application using them.
These features allow system designers to include:
• Simplified field programmability using two-wire
• Debugging using ICSP
• Programming and debugging capabilities using
• JTAG boundary scan testing for device and board
PIC32 devices incorporate two programming and diag-
nostic modules, and a trace controller, that provide a
range of functions to the application developer.
