GETTING STARTED WITH PIC32

Chapter 1. PIC32 Features

1.1 INTRODUCTION

The PIC32 is a 32-bit family of general purpose microcontrollers from Microchip

Technology. It offers 80+ DMIPS performance with a wide variety of on-chip periph-

erals. It employs industry leading M4K MIPS32 core from MIPS Technologies, Inc.

All members in the PIC32 family use programming interface similar to other Micro-

chip PIC

microcontrollers. In addition, PIC32 microcontrollers are pin-to-pin com-

patible with the PIC24FJ128GA family of 16-bit microcontrollers.

1.2 HIGHLIGHTS

The PIC32 family offers a number of features to enable a wide variety of applications.

The following subsections list all the key features grouped in major categories.

Performance:

• Up to 80 MHz, MIPS M4K 32-bit core with 5 stage pipeline

• High-performance hardware multiply/divide unit – 1 multiply per clock

• Programmable user and kernel memory partition for enhanced application stability

• Multiple register sets for reduced interrupt latency

• Hardware assisted single-cycle register bits manipulations

• 128-bit wide Flash memory to shorten individual instruction fetch time

• 256 bytes of high-speed cache memory with instruction and ROM data prefetch

buffer

• Available DMA controller with integrated CRC calculation and pattern-based

transfer termination

• Includes USB On-The-Go controller for USB device, host, or dual-role

applications

• USB controller has own dedicated DMA interface

Power Management:

• 2.3 to 3.6V operation

• Full-speed operation over entire voltage range

• Various low-power modes including RUN, IDLE and SLEEP

• I/O transfers via DMA in IDLE mode

• Programmable peripheral clock

• Individual peripheral ON/OFF control and operation during IDLE mode

• Multiple clock sources

Scalability:

• Industry known MIPS32-compatible M4K CPU core with 5 stage pipeline

• Large family of devices with Flash memory options from 32 KB to 512 KB

• Pin compatible with 64/100 pin PIC24FJXXXGA family of 16-bit microcontrollers
