Overview

The PIC32MX795F512L-80I/PT is a high-performance 32-bit microcontroller featuring a MIPS32 M4K core operating at 80MHz. It is a highly integrated device equipped with 512KB of Flash and 128KB of RAM, specifically designed for connectivity-heavy applications including Ethernet, CAN, and USB OTG.

Why Choose This Part

This MCU offers a robust connectivity suite including 5x UART, 4x SPI, and 5x I2C ports, making it ideal for multi-protocol environments. Its 5V-tolerant I/O pins simplify integration with legacy industrial hardware while the MIPS16e mode can reduce code size by up to 40 percent.

Applications

Industrial Gateways
Utilizes integrated Ethernet MAC and dual CAN 2.0B modules to bridge factory floor networks with IT infrastructure.
USB Host Controllers
The USB 2.0 Full-Speed OTG engine allows the device to act as a host for flash drives or human interface devices.
Embedded Audio Processing
Leverages DSP instructions and single-cycle MAC operations to perform basic signal filtering and audio playback tasks.
Human Machine Interface (HMI)
Provides 85 I/O pins and a 16-channel 10-bit ADC to manage complex control panels and sensor arrays.

Getting Started

Begin development using the MPLAB X IDE and the XC32 compiler. For hardware evaluation, the PIC32 Ethernet Starter Kit II provides a direct path to testing the integrated MAC and USB capabilities. A hardware debugger such as the MPLAB ICD 4 or PICkit 4 is required for real-time debugging via the ICSP interface.
