Raspberry Pi RP2350A

RP2350 is the new high-performance, secure microcontroller from Raspberry Pi. With a higher core clock speed, double the on-chip SRAM, more powerful Arm cores, optional RISC-V cores, new security features, and upgraded interfacing capabilities, RP2350 delivers a significant performance and feature boost over its predecessor, RP2040.

RP2350 provides a comprehensive security architecture, built around Arm TrustZone for Cortex-M, and incorporating signed boot, 8KB of antifuse OTP for key storage, SHA-256 acceleration, a hardware TRNG, and fast glitch detectors. These features, including the secure boot ROM, are extensively documented and available to all users without restriction: this transparent approach, which contrasts with the “security through obscurity” offered by legacy vendors, allows professional users to integrate RP2350 into products with confidence.

The unique dual-core, dual-architecture capability of RP2350 allows users to choose between a pair of industry-standard Arm Cortex-M33 cores, and a pair of open-hardware Hazard3 RISC-V cores. Three high-performance Programmable I/O (PIO) co-processors, with a total of twelve independent state machines, support software-defined interfacing, with little or no CPU overhead.

RP2350 offers best-in-class performance for a vast range of applications, from cost optimised embedded computing, to secure applications requiring trusted firmware, to industrial IoT deployments with demanding I/O requirements. It is available in four package variants: with 30 or 48 GPIO pins, and with or without 2MB stacked flash memory.
