RP2040 Microcontroller

The RP2040 is the microcontroller chip at the heart of the Raspberry Pi Pico. Designed by Raspberry Pi, this high-performance, low-cost chip brings powerful computing to embedded applications in a compact 7mm × 7mm package built on 40nm silicon.

With dual ARM Cortex-M0+ cores, flexible programmable I/O, and six independent RAM banks connected by a fully connected bus fabric, RP2040 enables cores and DMA engines to operate in parallel without contention.
