Raspberry Pi has announced the launch of the RP2350 microcontroller, which is the core of the tiny Raspberry Pi Pico 2 board that debuted last August. The RP2350 is also used in a number of other products, such as the Pico W5 microboard.
The microcontroller contains two Arm Cortex-M33 and two RISC-V Hazard3 cores with a clock frequency of 150 MHz. The required cluster is selected during the initialization of the product, i.e., it is impossible to use Cortex-M33 and RISC-V blocks simultaneously. The device has 520 KB of SRAM memory. Arm TrustZone is responsible for security.

Raspberry Pi RP2350 provides support for 2×UART, 2×SPI, 2×I2C, 24×PWM, etc. The product is software compatible with the Raspberry Pi RP2040 microcontroller. There are RP2350A (QFN-60; 7×7 mm; 30×GPIO) and RP2350B (QFN-80; 10×10 mm; 48×GPIO) versions available. In addition, RP2354A and RP2354B modifications in similar versions, supplemented with 2 MB of Stacked Flash memory, are being prepared for release.
