Introduction to PIC32

The PIC32 is a Microchip's 32-bit Microcontroller, introduced in 2007. The PIC32 is based on the MIPS (Microprocessor without Interlocked Pipeline Stages) processor. PIC32 equipped with highly efficient internal bus architecture, and advanced instruction caching. PIC32 MCUs offer a range of general purpose and integrated connectivity peripherals including Ethernet, CAN, and USB host/device/On-The-Go. Integrated flash memory ranges from 32K to 512K and on-board RAM ranges from 8k to 128k.

The PIC32 family is supported by Microchip's MPLAB® development environment and well-known industry tools and software providers. Microchip customers benefit from the extensive offering of free software libraries, commonly available in source code form, such as graphics, TCP/IP, USB, encryption, file systems, and digital signal processing software. Most software stacks are compatible across numerous Microchip microcontroller and digital signal processor families. The MPLAB development environment spans the entire Microchip portfolio of over 600 Microcontrollers thus enabling you to use a single tool chain from the lowest cost 8-bit MCU to the highest performing and largest memory PIC32 MCU.
