【Product Introduction】

The Raspberry Pi Pico 2 is an MCU development board based on the new Raspberry Pi RP2350 dual-core RISC-V or dual-core Cortex-M33 microcontroller with 520 KB on-chip SRAM, a 4MB flash, a micro USB port for power and programming and the same GPIO headers as the Raspberry Pi Pico board with an RP2040 dual-core Cortex-M0+ microcontroller with 264KB SRAM.

The RP2350 embeds both an open-source Hazard3 RISC-V dual-core CPU and a dual-core Cortex-M33, but only one cluster can be used at a given time. Apart from the faster MCU cores and higher SRAM capacity, the RP2350 is about the same as the RP2040, albeit it also adds one extra PIO block bringing the total to three. One important new feature is built-in security when using Arm Cortex-M33 cores with Trustzone and other security features.

Developers can effortlessly migrate their code and hardware designs to the new Pico 2, benefiting from enhanced performance and expanded capabilities without the need for extensive modifications. 

[A More Powerful MCU Dev Board

Dual-Core ARM Cortex-M33]

Raspberry Pi Pico comes with dual ARM Cortex-M0+, while the new Pico 2 comes with a Dual-Core ARM Cortex-M33 and a Dual-Core RISC-V Hazard3. Flexible clocking system, with configurable up to a maximum speed of 150MHz! This tiny MCU comes with a whopping 520 Kbyte of SRAM, an external QSPI Flash with a capacity of 4 MByte, and enhanced eXecute in Place (XIP v2). Larger RAM and Flash size enable you to write high-level programming languages like MicroPython and CircuitPython for Raspberry Pi Pico 2.
