STMicroelectronics has announced its latest generation of power-saving microcontrollers (MCUs), the STM32U5 series, to meet demanding power/performance requirements for smart applications including wearables, personal medical devices, home automation and industrial sensors.

The STM32 MCUs, built upon the energy-efficient Arm Cortex-M processors, are already used in domestic appliances, industrial controls, computer peripherals, communication devices, and equipment managing smart cities and infrastructure. The STM32U5 series teams the efficient Arm Cortex-M33 core with ST’s innovative power-saving features and on-chip IP, cutting down energy demand while pumping up performance. The line also adds state-of-the-art features for today’s applications, including cybersecurity with hardware-based protection targeting PSA and SESIP (Security Evaluation Standard for IoT Platforms) assurance level 3, as well as graphics accelerators for rich user experiences.

The incorporation of Arm technology provides good energy efficiency and security, while developers can also utilise the Arm Keil MDK for energy optimisation. The MCUs should thus enable users to create smart consumer and industrial products that deliver high energy ratings, performance and cyber protection.
