As seen on the Raspberry Pi Pico 2, the RP2350A microcontroller from Raspberry Pi offers significant enhancements over RP2040, whilst continuing to provide their signature values of high-performance, low-cost, accessible computing, distilled into an extraordinary microcontroller.
The unique dual-core, dual-architecture capability of RP2350 provides a pair of industry-standard Arm Cortex-M33 cores with hardware single-precision floating point and DSP instructions @150MHz, and a pair of open-hardware Hazard3 RISC-V cores, selectable in software or by programming the on-chip OTP memory.
The RP2350A has a comprehensive security architecture, built around Arm TrustZone for Cortex-M, along with a second-generation PIO subsystem that provides flexible interfacing with no CPU overhead.
This is the RP2350A variant, offering 30 GPIO in a 7x7 QFN 60-pin package.
We also stock the RP2350B which offers 48 GPIO in a 10x10 QFN 80-pin package.
Important RP2350 Design Guidelines
- Please read and follow the RP235x design guide
- Please refer to the datasheet, including errata and our reference design in KiCAD format
- Please use the 12 MHz Abracon ABM8-272-T3 crystal oscillator
- If using the on-chip SMPS, please use the custom polarised inductor from Abracon (AOTA-B201610S3R3-101-T) and orient it according to the instructions in the design guide
