The STM32L562 microcontroller from STMicroelectronics offers a broad range of security capabilities for OEMs to provide better protection for IoT-connected applications.
Operating at clock frequencies up to 110MHz, the STM32L562 is based on the Arm® Cortex®-M33, a security-enhanced processor core which gives MCUs the ability to implement Arm TrustZone® hardware-based security. The TrustZone trusted computing platform creates a protected execution environment for connected products and their sensitive code such as key storage, thus blocking attempts to corrupt devices or software. A second, independent execution environment allows for the running of untrusted code.
An MCU which has TrustZone capability is already a strongly protected device, but ST has added the ability to include or exclude each I/O, peripheral, or area of Flash or SRAM from TrustZone protection. This allows sensitive workloads to be fully isolated for maximum security.
In addition, ST has built on the TrustZone capabilities to add:
The MCU also features active tamper detection and secure firmware installation. This comprehensive set of security features and capabilities has enabled ST to gain PSA Certified Level 2 status for the STM32L562.
These security capabilities are combined in the STM32L562 devices with ultra low-power performance to enable the MCUs to deliver high operating speed and long run times, whether powered by coin cells or even through energy harvesting. Low-power techniques deployed in the MCUs include:
