Overview

The PIC32MX270F256B-I/SP is a 32-bit MIPS32 M4K-based microcontroller featuring 256KB of Flash and 64KB of RAM in a through-hole PDIP package. It includes integrated USB 2.0 OTG support and specialized peripherals like Peripheral Pin Select (PPS) for flexible I/O mapping.

Why Choose This Part

This MCU offers a high memory-to-pin ratio with 256KB Flash in a small 28-pin footprint. The Peripheral Pin Select (PPS) feature allows engineers to remap digital peripherals to almost any I/O pin, greatly simplifying PCB layout or breadboard wiring.

Applications

USB Device Controllers
Utilize the integrated USB OTG peripheral for creating custom HID, CDC, or MSD class devices.
Digital Audio Processing
Leverage the I2S interfaces and DSP instructions for basic audio filtering and playback applications.
Rapid Breadboard Prototyping
The 28-pin SPDIP package allows for direct insertion into breadboards for 32-bit application development without custom PCBs.
Capacitive Touch Interfaces
Implementation of mTouch sensing for buttons and sliders in consumer electronic controls.
