Overview

The PIC32MX270F256B-50I/SP is a high-performance 32-bit microcontroller featuring a MIPS32 M4K core running at up to 50MHz. It is uniquely packaged in a 28-pin SPDIP, making it one of the most powerful microcontrollers available for through-hole prototyping and breadboarding. The device includes 256KB of Flash, 64KB of RAM, and a full-speed USB 2.0 OTG controller.

Why Choose This Part

This MCU provides a substantial 64KB of SRAM and 256KB of Flash in a hobbyist-friendly through-hole package. It features 5V tolerant pins, which simplifies interfacing with older digital logic and industrial sensors. The inclusion of DMA and a hardware CRC engine allows for efficient data handling without stalling the main CPU core.

Applications

USB Device Development
Ideal for creating custom USB peripherals like HID devices, CDC serial ports, or mass storage classes due to the integrated USB 2.0 OTG controller.
Digital Signal Processing
Leverages the MIPS32 M4K core's hardware-based DSP instructions for audio filtering, sensor data processing, and FFT calculations.
Rapid Prototyping
The 28-pin SPDIP package allows for direct insertion into breadboards or IC sockets without needing SMD adapters.
Industrial Control
Utilizes 5V tolerant I/O and multiple serial interfaces (UART, SPI, I2C) to interface with legacy 5V sensors and industrial equipment.
