双核Cortex-M33和RISC-V
从方便开展嵌入式教育的角度出发，树莓派基金会特别在RP2350中添加了两个Cortex-M33和两个RISC-V核。在芯片的启动阶段，用户可以从4个核心中任选两个，由此我们产生了以下的组合：
双核Cortex-M33 双核RISC-V 一个Cortex-M33 + 一个RISC-V
其中RISC-V核是Harzard3（https://github.com/Wren6991/Hazard3）。
Hazard3 is a 3-stage RISC-V processor, implementing the RV32I instruction set and the following optional extensions:
M: integer multiply/divide/moduloA: atomic memory operations, with AHB5 global exclusivesC: compressed instructionsZicsr: CSR accessZba: address generationZbb: basic bit manipulationZbc: carry-less multiplicationZbs: single-bit manipulationZbkb: basic bit manipulation for scalar cryptographyZcb: basic additional compressed instructionsZcmp: push/pop instructionsDebug, Machine and User privilege/execution modes
Privileged instructions
ecall,ebreak,mretandwfiPhysical memory protection (PMP) with up to 16 naturally aligned regions
相对成熟的Cortex-M33来说，它是一个“10小时前”才发布1.0版的小婴儿。
RP2350的SRAM几乎翻倍，达到了520KByte的级别
RP2350的标称最大频率是150MHz，实测下来可以跟RP2040一样轻松超频到250MHz
官方声称RP2350与RP2040在软件和硬件上都是向前兼容的（RP2350兼容RP2040的软件和硬件）
这意味着市面上针对RP2040设计的外设模块，仍然可以直接在RP2350上使用。
RP2350的输入电压是1.8v~5.5v。
Pico2 板载了4MByte的外部Flash，相对Pico的2MHz扩充了一倍 Pico2 官方标称5美元
