Raspberry Pi RP2040 Microcontroller Chips

Raspberry Pi RP2040 Microcontroller Chips feature sizeable on-chip memory, a symmetric dual-core processor complex, deterministic bus fabric, and a rich peripheral set. These chips are augmented with a unique programmable I/O (PIO) subsystem for power and flexibility and include detailed documentation, a polished MicroPython port, and a UF2 bootloader in ROM. The cost-effective modules are designed to deliver high performance and ease of use. The RP2040 is a stateless device, with support for cached execute-in-place from external QSPI memory. This design enables a choice of an appropriate density of non-volatile storage for applications. Raspberry Pi RP2040 Microcontroller Chips are manufactured on a modern 40nm process node, resulting in low dynamic power consumption and low leakage. The low-power modes support extended-duration operation on battery power. The RP2040 series is available in a QFN-56 package with a -20°C to +85°C operating temperature range.
