RISC-V MCU certified for PSA L2 security

“PSA certification aligns with upcoming regulations including the European Union’s Cyber Resilience Act, the US Cybersecurity Improvement Act, the EU Radio Equipment Directive, and the UK Product Security and Telecommunications Infrastructure [regime],” according to Espressif. “Achieving PSA Level 2 certification signifies that the ESP32-C6’s PSA root-of-trust has undergone laboratory evaluation, demonstrating its resilience against scalable software attacks.”

The device is a wireless microcontroller, with radios for Wi-Fi 6, Bluetooth 5 LE and IEEE 802.15.4 (Zigbee 3.0 and Thread 1.3). Processing comes from two 32bit RISC-V cores, one for performance (160MHz, four stage pipeline) and one for power-saving (20MHz, two-stage pipe). In-package flash is optional.

Its security features include physical memory protection and access permission management for memory isolation and privilege separation, on-board private key generation, secure boot, flash encryption, hardware accelerators for AES, SHA, RSA and ECC, and a secured JTAG Mode.
