If you are like me, you probably don’t remember, but back in 2017 Arm announced the Platform Security Architecture (PSA) that defines a set of requirements to secure low cost Internet of Things devices. There’s now at least one PSA compliant microcontroller, as Cypress Semiconductor introduced their PSoC 64 Secure MCU at Embedded World 2019 last month. The press release claims that PSoC 64 MCU family is one of “the first Arm Cortex-M processors to be certified as Level 1 compliant within the Arm Platform Security Architecture (PSA) certification scheme, PSA Certified, utilizing a secure Trusted Firmware-M (TF-M) implementation integrated into the Arm Mbed OS open-source embedded operating system”. PSoC 64 secure MCU key features and specifications: Arm Cortex-M4F core with 22‑µA/MHz active power consumption Optional Arm Cortex-M0+ core with 15‑µA/MHz power consumption System Memory – 160KB to 1MB SRAM Storage – 512KB to 2MB flash Security HW Cryptography – […]
