Overview

The PIC32MX470F512H-I/PT is a high-performance 32-bit microcontroller based on the MIPS32 M4K core, featuring 512KB of Flash and 128KB of RAM. It is designed for applications requiring integrated USB 2.0 Full-Speed OTG support and high computational throughput at clock speeds up to 120MHz. The device includes 53 GPIO pins and a versatile set of peripherals including 5 UARTs and a 28-channel 10-bit ADC.

Why Choose This Part

This MCU offers a robust balance of memory and connectivity, including 5V-tolerant I/O pins which simplify interfacing in mixed-voltage environments. The inclusion of DSP instructions and a 120MHz maximum clock speed provides significant headroom for math-intensive tasks compared to standard 8-bit or 16-bit controllers.

Applications

USB Connectivity Hubs
Utilizing the integrated USB 2.0 OTG controller to manage data exchange between peripherals and host devices.
Industrial Control Panels
Leveraging the 53 GPIOs and 5V-tolerant inputs to interface with industrial sensors and legacy 5V logic systems.
Audio Processing Bridges
Using DSP instructions and I2C/SPI interfaces to perform real-time filtering and digital audio routing.
Environmental Monitoring
Employing the built-in temperature sensor and 28-channel ADC for dense multi-point sensor data acquisition.

Getting Started

Development is primarily supported through Microchip MPLAB X IDE and the XC32 compiler. For rapid prototyping, the PIC32 USB Starter Kit II or the Curiosity PIC32MX470 Development Board provides an integrated debugger and access to the USB OTG features. Engineers should utilize the MPLAB Harmony framework for simplified driver integration and USB stack management.
