Cypress Semiconductor announced a new line of its PSoC 6 microcontrollers designed to give Internet of Things designers confidence in the security of their applications. The new PSoC 64 Secure MCUs integrate robust, standards-based system layer security software with the hardware layer features available in the ultra-low-power PSoC 6 architecture. Specifically, PSoC 64 Secure MCU devices provide an isolated root-of-trust with true attestation and provisioning services. In addition, the line includes devices that deliver a pre-configured secure execution environment supporting the system software of various IoT platforms, providing TLS authentication, secure storage, and secure firmware management. The MCUs also include a rich execution environment for application development, with an embedded RTOS from Cypress’ ModusToolbox suite that manages communication with the secure execution environment.
PSoC 64 Secure MCUs are one of the first Arm Cortex-M processors to be certified as Level 1 compliant within the Arm Platform Security Architecture certification scheme, PSA Certified, utilizing a secure Trusted Firmware-M implementation integrated into the Arm Mbed OS open-source embedded operating system. Combined with the Arm PSA holistic set of threat models, security analyses, and hardware and firmware architecture specifications, designers can use PSoC 64 Secure MCUs with confidence in their secure applications. The line is ideal for cloud-connected products that require protection of user data and trustworthy firmware updates, including personal healthcare devices, medical and chronic disease management equipment, and home security solutions.
