RP2350
 |
RP2350 is a 32-bit dual ARM Cortex-M33 and Hazard3 RISC-V microcontroller integrated circuit by Raspberry Pi Ltd.[1] In August 2024, it was released as part of the Raspberry Pi Pico 2 board.[2]
Overview
[edit]Announced on 8 August 2024, the RP2350 is the second microcontroller designed by Raspberry Pi Ltd, after the RP2040.[2] 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, which are identified by the number of cores (2), the last digit of the core type (3), log₂ of the number of 16kB RAM blocks (5), log₂ of the number of 128 kB flash storage blocks (0 or 4), and a letter denoting package type (A or B):[3]
- 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 2 MB of flash
- RP2354B, which is the RP2350B with stacked 2 MB of flash
At announcement time, seventeen other manufacturers had products expected to be available within a month:
