PIC32 is a family of 32-bit microcontrollers made by Microchip Technology. They contain a MIPS32 core, developed by MIPS Technologies.

PIC32 microcontrollers have been announced in November 2007

Features include

  • Execution speed up to 80 MHz
  • Flash size up to 512 kByte
  • Programs can be executed from RAM
  • Available in different packages, including Dual in-line (DIP)

A PICkit3 is required to program these microcontrollers. Microchip offers an IDE (MPLAB X) which includes a modified GCC compiler (xc32). It is possible to compile programs for PIC32 using the free mips-elf-gcc compiler as well.
