Raspberry Pi RP2350 Microcontrollers (MCUs)

Raspberry Pi RP2350 Microcontrollers (MCUs) are high-performance and secure MCUs with a higher core clock speed, double the on-chip SRAM, and optional RISC-V cores. These MCUs are built around dual Arm^® Cortex^®-M33 cores with hardware single-precision floating point and DSP instructions @150MHz. The RP2350 MCUs include a second-generation PIO subsystem that provides flexible interfacing with no CPU overhead. These MCUs consist of the security architecture that is built around Arm TrustZone for Cortex-M. The unique dual-core and dual architecture capability of these MCUs offer a pair of Arm Cortex-M33 cores and a pair of open-hardware Hazard3 RISC-V cores. The dual-architecture is selectable via software or by programming the on-chip OTP memory. The RP2350 MCUs are used in embedded computing and industrial IoT deployments with demanding I/O requirements.
