Raspberry Pi SBC touts RISC-V cores

The Raspberry Pi Pico 2 single-board computer is powered by the RP2350 MCU, featuring two Arm cores or optional RISC-V cores. This $5 computer board also boasts higher clock speeds, twice the memory, enhanced security, and upgraded interfacing compared to its predecessor, the Pico 1.

Designed by Raspberry Pi, the RP2350 MCU leverages a dual-core, dual-architecture with a pair of Arm Cortex-M33 cores and a pair of Hazard3 RISC-V cores. Users can select between the cores via software or by programming the on-chip OTP memory. Both the Arm and RISC-V cores run at clock speeds of up to 150 MHz.

Pico 2 offers 520 kbytes of on-chip SRAM and 4 Mbytes of onboard flash. A second-generation programmable I/O (PIO) subsystem provides 12 PIO state machines for flexible, CPU-free interfacing.

The security architecture of the Pico 2 is built around Arm TrustZone for Cortex-M and includes signed boot support, 8 kbytes of on-chip antifuse OTP memory, SHA-256 acceleration, and a true random number generator. Global bus filtering is based on Arm or RISC-V security/privilege levels.

Preorders of the Pico 2 are being accepted now through Raspberry Pi’s approved resellers. Even though Pico 2 does not offer Wi-Fi or Bluetooth connectivity, Raspberry Pi expects to ship a wireless-enabled version before the end of the year.
