RP2350
Raspberry Pi Foundation's second microcontroller Raspberry Pi Pico 2 and the chipset RP2350.
Raspberry Pi released a new microcontroller, the RP2350, 8/82024 in conjunction with DEF CON 23 (the official badge uses the new chip). A new board was also released, the Raspberry Pi Pico 2. The RP2350 comes in four packages, two with 30 pins and two with 48 pins providing additional GPIO the secondary versions add 2MB of flash.
The new chips use two Arm Cortex M33 cores + floating point unit and also have two RISC-V HAZARD3 cores (only any two cores usable at a time). The clock speed is bumped to 150 MHz. With the new architecture and floating point along with 3 PIO units, the speed is about double at stock clocks, while using less power. Besides Raspberry Pi Pico 2, there are over 30 boards which have been announced at launch from a variety of vendors.
Why is the chip called RP2350?
RP 2 3 5 0 RP == Raspberry Pi 2 = Number of cores 3 = Type of core (e.g., Cortex-M33) 5 = floor (log2(nonvolatile/ 128 kB)) 0 = floor(log2(nonvolatile / 128 kB))
