SC1511-A4

SC1511-A4 is a RP2350 new high-performance, secure microcontroller. With a higher core clock speed, double the on-chip SRAM, more powerful Arm cores, optional RISC-V cores, new security features, and upgraded interfacing capabilities, RP2350 delivers a significant performance and feature boost over its predecessor, RP2040. The RP2350 provides a comprehensive security architecture, built around Arm TrustZone for Cortex-M, and incorporating signed boot, 8KB of antifuse OTP for key storage, SHA-256 acceleration, a hardware TRNG, and fast glitch detectors. It offers best-in-class performance for a vast range of applications, from cost optimised embedded computing, to secure applications requiring trusted firmware, to industrial IoT deployments with demanding I/O requirements.
