RP2350

RP2350 is a 32-bit dual ARM Cortex-M33 and Hazard3 RISC-V microcontroller integrated circuit by Raspberry Pi Ltd. In August 2024, it was released as part of the Raspberry Pi Pico 2 board.

Overview

Announced on 8 August, the RP2350 is the second microcontroller designed by Raspberry Pi Ltd, after the RP2040. The microcontroller is low cost, with the Raspberry Pi Pico 2 being introduced at US$5 and the RP2350 itself costing as little as US$0.80 in bulk. The microcontroller is software-compatible with the RP2040 and can be programmed in assembly, C, C++, Free Pascal, Rust, MicroPython, CircuitPython, and other languages.

The RP2350 comes in four versions:

• RP2350A with 30 GPIO in a 7 × 7 mm 60-pin package
• RP2350B with 48 GPIO in a 10 × 10 mm 80-pin package
• RP2354A, which is the RP2350A with stacked 2MB of flash
• RP2354B, which is the RP2350B with stacked 2MB of flash

At announcement time, seventeen other manufacturers had products expected to be available within a month:

• 4D Systems
• Adafruit
• Bus Pirate
• Cytron
• Hellbender
• Ignys
• Invector Labs
• Melopero
• NewAE
