Raspberry Pi has stepped up its chip development with a quad core microcontroller with two ARM Cortex-M33 cores and two in-house RISC-V cores.
The $5 Raspberry Pi Pico 2 board uses the RISC-V RP2350 microcontroller and will be followed by a wireless version, the Pico 2 W with a modem from Infineon Technologies.
The RP2350 is twice the die size, has a higher core clock speed at 150MHz, twice the memory at 520KB of SRAM in ten banks and new security features compared to the RP2040 launched over three years ago with two M0+ cores. The die size is 5.3mm2, versus 2mm2 for RP2040, but the smallest version RP2350A will be just ten cents more expensive, costing $0.80 in 3,400-unit reels, or $1.10 in single-unit quantities.
