STMicroelectronics has introduced new STM32U3 microcontrollers with cutting-edge power-saving innovations that ease deployment of smart connected tech, especially in remote locations.
The latest MCUs are aimed at IoT devices, which must typically operate for extended periods without maintenance and with limited energy from a coin cell or ambient solar or thermoelectric source. Typical applications include utility meters, healthcare devices such as glucose meters and insulin pumps, animal care monitors, forest-fire sensors, and industrial sensors.
In addition to its extreme energy efficiency, the STM32U3 series meets the needs of IoT devices by providing robust cyber protection using the latest hardware security techniques. The MCUs are designed to confine secret keys permanently in secure memory, eliminating vulnerable CPU fetches. In addition, attestation credentials for each device are provisioned by ST during manufacturing before leaving the factory. All those security mechanisms, in addition to the SESIP3 and PSA Level3 certifiable security assets, such as cryptographic accelerators and TrustZone isolation all contribute to a secure product.
