Overview

The PIC32MX460F512L-80I/PT is a high-performance 32-bit microcontroller featuring a MIPS32 M4K core running at 80MHz with 512KB of Flash and 32KB of RAM. It is designed for applications requiring integrated USB 2.0 OTG capabilities and a wide range of serial communication peripherals in a 100-pin TQFP package.

Why Choose This Part

This MCU offers a 5-stage pipeline and MIPS16e mode for improved code density and execution efficiency. The inclusion of a prefetch cache and atomic SET/CLEAR/INVERT operations allows for high-speed bit manipulation and reduced CPU overhead during peripheral management.

Applications

USB Peripheral Controllers
Utilizing the integrated USB 2.0 OTG controller for PC peripherals, custom HID devices, or mass storage interfaces.
Industrial Gateway Systems
Managing multiple communication protocols including I2C, SPI, and UART to bridge industrial sensors with higher-level networks.
User Interface Controllers
Driving graphical or character LCDs via the Parallel Master Port (PMP) while processing user input through the 16-channel 10-bit ADC.
