The RP2040 is Raspberry Pi’s debut microcontroller, bringing the company’s hallmark values—high performance, low cost, and ease of use—to the microcontroller space. Featuring a symmetric dual-core processor, large on-chip memory, a deterministic bus fabric, and a versatile set of peripherals enhanced with the unique Programmable I/O (PIO) subsystem, RP2040 offers professional users exceptional power and flexibility.
Its flexible I/O allows connection to almost any external device, while its high-performance cores excel at integer workloads. The chip’s low cost helps lower the barrier to entry for both beginners and hobbyists.
With six independent SRAM banks and a fully connected internal switch, RP2040 enables cores and DMA engines to operate in parallel without contention, ensuring maximum efficiency. Its compact 7 mm × 7 mm package contains just two square millimeters of 40nm silicon, combining Raspberry Pi’s philosophy of efficient, low-cost computing in a tiny footprint.
RP2040 also offers an approachable development experience, with detailed documentation, a polished MicroPython port, and a UF2 bootloader in ROM, making it ideal for beginners. As a stateless device, it supports cached execute-in-place from external QSPI Flash, allowing you to select the appropriate storage density for your application while benefiting from low-cost Flash options. Manufactured on a modern 40nm process, the RP2040 delivers high performance, low dynamic power, minimal leakage, and multiple low-power modes for battery-powered applications.
