Raspberry Pi Pico 2 and a new micro-controller with RISC-V and Arm?

I haven't made the jump to playing with RISC-V yet, I'm wondering what the advantages are there.

And this makes it quad-core, right?

Crazy.

I have a lot of reading to do!

 Hardware Design with the RP2350 /  RP2350 Datasheet /  RP2350 Product Brief 

 Of course there's the Pico 2:  Raspberry Pi Pico 2 Datasheet  - I admit I haven't touched a Pico 1 yet.

What am I missing out on?

  • Wow. never knew this was coming!
    I have explored both Pico and Pico w in the last few months. PIO is a nice little feature to handle gpios in a much faster CPU independent way ( BIT BANG more peripherals with out CPU )
    In Pico there were 8 PIO state machines. Its been increased to 12 in pico2.

    But something I dont understand is why dual core ARM or RISCV? Did I get it wrong ? What I understand is its either dual core ARM Cortex M33 or dual core Hazard3g RISCV. But why?
    Why can't it be one of it? Adding two processor will consume more silicon space right? 
    May be It's part of their RISCV migration plan? Pico 2 is binary compatible with Pico1. May be A Pico 3 in the future with only RISCVs?!!
    Anyways so happy to see RISCV getting more traction. I think its the future ahead.

    Might have some influence, note from an investment page: Arm said it would buy USD 35m in shares, which builds on the stake they took in October (3.4%).
