SPIDER Automation Raspberry Pi RP2350B Microcontroller IC | Secure Dual-Core MCU
Description
SPIDER Automation Raspberry Pi RP2350B Microcontroller IC represents the pinnacle of secure microcontroller technology, engineered specifically for professional electronics developers, engineers, and prototype designers. Delivering a massive performance upgrade over the RP2040, the RP2350B features a unique dual-architecture layout allowing engineers to choose between industry-standard ARM Cortex-M33 or open-hardware Hazard3 RISC-V cores clocked up to 150 MHz.
It equips 520KB of on-chip SRAM and integrates an uncompromising hardware security architecture—including Arm TrustZone, signed boot, SHA-256 acceleration, and 8KB of antifuse OTP key storage. With expanded GPIO and ADC channels plus an additional Programmable I/O (PIO) core, the RP2350B provides the ultimate secure, versatile foundation for custom embedded hardware and modern IoT devices.
Important RP235x Design Guidelines
To ensure correct operation, please adhere to the following guidelines when designing with RP235x microcontrollers:
