DatasheetProduct Overview
The individual RP2350 ICs represent Raspberry Pi’s next-generation microcontroller, which offers a blend of high performance, robust security, and remarkable flexibility - all at an impressively low cost. Building on the success of the RP2040, the RP2350 features dual-core processing with a unique twist: you can choose between two Arm Cortex-M33 cores or two open-source Hazard3 RISC-V cores, selectable via software or OTP configuration. Running at 150MHz with 520KB of SRAM, this chip is ideal for demanding applications such as real-time control, edge AI, and secure IoT systems.
The RP2350 doesn’t just pack power—it’s built for versatility. It offers up to 48 GPIOs, 24 PWM channels, 12 PIO state machines, and a USB 1.1 controller with support for both host and device modes. It’s also software-compatible with the RP2040, making it easy to migrate existing projects. Security is a standout feature, with Arm TrustZone, hardware SHA-256, optional boot signing, and fault injection mitigations—all backed by Raspberry Pi’s commitment to transparency and open documentation. 
Whether you’re building a custom board or prototyping with the Raspberry Pi Pico 2, the RP2350 is ready to power your next innovation. Available in multiple package options, including variants with stacked 2MB QSPI flash, this microcontroller is designed to scale from hobbyist projects to industrial-grade deployments. And with a production guarantee through at least 2045, it’s a chip you can count on for the long haul.
