Raspberry Pi Pico 2 builds on the huge success of the original Raspberry Pi Pico product and its derivatives, which were launched in 2021 and 2022.
It is powered by the brand-new RP2350 microcontroller platform, designed by Raspberry Pi
Raspberry Pi Pico 2 is our new $5 microcontroller board, built on RP2350: our new highperformance, secure microcontroller. With a higher core clock speed, double the on-chip
SRAM, double the on-board flash memory, more powerful Arm cores, optional RISC-V cores, new security features, and upgraded interfacing capabilities, Raspberry Pi Pico
2 delivers a significant performance and feature boost, while retaining hardware and software compatibility with earlier members of the Raspberry Pi Pico series.
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, and Raspberry Pi Pico 2, 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. Programmable in C / C++ and Python, and with detailed documentation, Raspberry Pi Pico 2 is the ideal microcontroller board for enthusiasts and professional developers alike.
Enter RP2350
Two years ago, with the RP1 I/O controller for Raspberry Pi 5 in the bag, the Raspberry Pi chip team started work on what would become RP2350.
This is a vastly more sophisticated design than RP2040.
And the Raspberry Pi team stayed true to their affordable roots: although their silicon die now measures an extravagant 5.3mm2, versus 2mm2 for RP2040, RP2350A will be just ten cents more expensive, costing $0.80 in 3,400-unit reels, or $1.10 in single-unit quantities. RP2350B will cost ten cents more than RP2350A, while the RP2354 variants will cost just twenty cents more than their flashless counterpart.
RP2350 will be generally available in volume before the end of 2024.
