Looking for an upgrade from the RP2040? The Raspberry Pi RP2350A microcontroller has got you covered! With impressive enhancements and signature cost-effective, accessible computing values, this extraordinary microcontroller boasts a unique dual-core, dual-architecture capability. Featuring industry-standard Arm Cortex-M33 cores, hardware single-precision floating point and DSP instructions @150MHz, and open-hardware Hazard3 RISC-V cores, this microcontroller also offers a comprehensive security architecture and a second-generation PIO subsystem for seamless interfacing. Choose between 30 GPIO in a compact 7x7 QFN 60-pin package or 48 GPIO in a larger 10x10 QFN 80-pin package with the RP2350B variant.
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
