RP2040 in RP2040 / RP2350 Family
The RP2040 is the debut microcontroller designed by Raspberry Pi, featuring a unique dual-core ARM Cortex-M0+ architecture. It is designed to provide high performance for integer workloads and exceptional I/O flexibility through its Programmable I/O (PIO) subsystem. Built on a 40nm process, this chip balances power efficiency with high-speed processing, making it a foundational component for the Raspberry Pi Pico and a wide range of industrial and consumer electronics requiring versatile peripheral control.
Variants in This Sub-Family
The RP2040 sub-family is currently centered around a single silicon revision, though implementation varies across third-party modules. While the core silicon features a fixed 264 KB SRAM and no internal Flash, different hardware implementations vary the external QSPI Flash capacity, ranging from 2 MB to 16 MB. Physical variants typically differ in package size and GPIO breakout rather than internal logic changes.
