The RP2350 is Raspberry Pi’s second-generation in-house microcontroller design. The Raspberry Pi RP2350 is a major upgrade over the earlier Raspberry Pi RP2040, boasting newer Arm Cortex-M33 cores running at a faster 150MHz, almost twice the static RAM (SRAM) plus support for external pseudo-static RAM (PSRAM), an additional programmable input/output (PIO) block, and more — but it also brings with it an architectural complexity: the presence of two RISC-V cores, based on the free and open source Hazard3 design, which can be chosen in place of the Arm cores or even split with one Arm and one RISC-V core running simultaneously.

New microcontroller boasts a choice of 150MHz Arm Cortex-M33 or RISC-V Hazard3 cores, a dedicated display peripheral, 520kB SRAM, and more. RP2350 is built using quad-core dual-architecture with two ARM and two RISC-V cores, but only two of those four cores can run at the same time. There is 520 Kb of SRAM memory on the chip and the new features include Arm TrustZone, 8 Kb OTP memory and Secure Boot support. The previous PR2040 had two Arm Cortex-M0+ cores with a maximum clock frequency of 133 MHz and 264 KB of SRAM memory. It is possible to integrate extra two megabytes of Flash to the same chip package.

“Raspberry Pi Pico 2 is our new $5 microcontroller board, built on RP2350: our new high-performance, secure microcontroller,” the company says of its latest launch. “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.”

For programming Raspberry Pi RP2350′shave Day-One Rust Support. Pallant says, “this is the first ever microcontroller launch with Rust support out-of-the-box.” Raspberry Pi Pico 2 board serves as a quick-start development platform.
