Second microcontroller generation New Microcontroller RP2350 from Raspberry Pi

By Susanne Braun | Translated by AI 1 min Reading Time

In mid-March 2025, the developers of Raspberry Pi released the second generation of their microcontroller platform, the RP2350. The chip builds on the RP2040 and offers more power, more security while maintaining high flexibility.

Since mid-March 2025, the second generation of the company's microcontroller, the RP2350, which was introduced in summer 2024 and is based on the technology of the successful RP2040, has been available through the usual Raspberry Pi distribution channels. The RP2350 features two Arm Cortex-M33 processors with 150 MHz, integrated floating-point and DSP support, and a security concept based on Arm TrustZone. With large on-chip SRAM and programmable I/O functions, the chip is ideal for applications in industrial, IoT, smart consumer products, and more.

Like all Raspberry Pi products, the RP2350 comes with comprehensive documentation, reference designs (e.g., for KiCAD), and practical guides for hardware integration. Special emphasis was placed on transparency in security: A public hacking challenge confirmed the robustness of the security features. Currently, the following variants are available:

  • RP2350A: 0.28 × 0.28 inches, QFN60 package

  • RP2350B: 0.39 × 0.39 inches, QFN80 package

Also this year, two more variants with integrated flash memory, the RP2354A and RP2354B, will be released, suitable for compact designs with limited space. With the new generation of the microcontroller, the predecessor RP2040 serves as the entry-level model when cost is crucial or only simple projects without specific floating-point or security functions are to be implemented. Accordingly, the RP2350 is the next step for more demanding and secure embedded projects, although the price is not too high. (sb)
