This family introduces a new line of Microchip devices:
a 32-bit RISC microcontroller family with a broad
peripheral feature set and enhanced computational
performance. The PIC32MX3XX/4XX family offers a
new migration option for those high-performance appli-
cations which may be outgrowing their 16-bit platforms.
1.1 Easy Migration
The PIC32MX family of microcontrollers was designed
to provide an easy migration path as the application
needs change.
The consistent pinout scheme used throughout the
entire family aids in migrating to the next larger device.
This is true when moving between devices with the
same pin count, or even jumping from 64-pin to 100-pin
devices.
The PIC32MX family is pin and peripheral compatible
with Microchip PIC24FJ128GA010 devices.
1.2 Core Features
1.2.1 32-BIT RISC ARCHITECTURE
Central to all PIC32MX3XX/4XX devices is the 32-bit
MIPS32 M4K CPU core, offering a wide range of
features, including the following:
• Up to 1.56 DMIPS/MHz
• 32-bit Address and Data paths
• 32-bit Linear (program space) addressing
• (2) thirty-two element 32-bit core register files
• Single-cycle multiply and high-performance divide
unit for 32-bit integer math
• 16 and 32-bit instructions, optimized for
high-level languages, such as ‘C’.
1.3 Power-Saving Technology
All of the devices in the PIC32MX family incorporate a
range of features that can significantly reduce power
consumption during operation. Key features include:
• On-the-Fly Clock Switching: The device clock
can be changed under software control to any of
the four clock sources during operation.
• Instruction-Based Power-Saving Modes: The
microcontroller can suspend all operations, or
selectively shut down its core while leaving its
peripherals active, with a single instruction in
software.
1.4 Communications
The PIC32MX incorporates a range of serial communi-
cation peripherals to handle a range of application
requirements. All devices are equipped with two inde-
pendent UARTs with built-in IrDA encoder/decoders.
There are also two independent SPI modules, and two
independent I²C modules that support both Master and
Slave modes of operation.
1.5 10-bit A/D Converter
The A/D Converter features 500 ksps maximum sample
rate. This configurable module incorporates a user-
selectable scan list and auto-convert functions to allow
acquisitions without processor intervention. Multiple A/D
trigger sources are user-selectable: timer event, external
pin, manual and auto-convert.
