Raspberry Pi has just unveiled its latest microcontroller unit, the RP2350, an exciting successor to the popular RP2040. This new MCU introduces significant upgrades, including a dual Cortex-M33 processor running at 150MHz and the introduction of the Hazard 3 RISC-V core, designed by Raspberry Pi’s Luke Wren in his spare time. Remarkably, this open-source core is available for download, offering developers a unique opportunity to dive into RISC-V architecture.
Security, performance, and power efficiency are the standout improvements. The RP2350 boasts larger memory, enhanced security features, and an OTP (one-time programmable) storage. For low-power applications, it shines—able to drop its power consumption to less than a tenth of the RP2040 in idle states, making it perfect for devices that need to wait for sensor inputs.
In addition, Raspberry Pi swapped the old regulator for a more efficient switching power supply, capable of delivering up to 200mA, while keeping the familiar PIO (Programmable I/O)—now with a third block and four more state machines.
By sticking with the proven TSMC 40nm process, Raspberry Pi reused much of its previous tech, speeding up development while ensuring the RP2350 is packed with cutting-edge features for makers and developers alike.
