Overview

The RP2040 is the first microcontroller designed by Raspberry Pi, featuring a dual-core ARM Cortex-M0+ processor running at up to 133MHz. It is a high-performance, low-cost silicon solution with a unique Programmable I/O (PIO) subsystem that allows for the creation of custom digital interfaces.

Why Choose This Part

The RP2040 offers exceptional flexibility through its 8 PIO state machines and a fully-connected AHB crossbar that prevents bus contention. Its large 264KB SRAM and support for up to 16MB of external QSPI flash provide significant headroom for complex applications compared to traditional M0+ devices.

Applications

Edge AI and Machine Learning
The dual-core architecture and 264KB of on-chip RAM support lightweight ML frameworks like TensorFlow Lite Micro for gesture or voice recognition.
Custom Digital Protocol Emulation
Using the PIO state machines, engineers can implement protocols like VGA, DVI, or custom LED drivers without loading the main CPU cores.
USB Device and Host Controllers
Built-in USB 1.1 support allows the chip to act as a HID device, mass storage class, or a host for various peripherals.
