Low-power MCUs offer advanced cybersecurity
Advanced MCUs feature Arm® embedded core and advanced cybersecurity, graphics, and peripherals for demanding consumer and industrial applications.

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

STM32 MCUs are built upon the highly energy-efficient Arm® Cortex®-M processors, are already in billions of domestic appliances, industrial controls, computer peripherals, communication devices, and equipment managing smart cities and infrastructure.

The latest STM32U5 series teams the efficient Arm Cortex-M33 core with ST’s innovative proprietary power-saving features and on-chip IP cutting down energy demand while pumping up performance. The line also adds new state-of-the-art features needed by today’s applications, including advanced cybersecurity with new 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.

ST has also created the STM32U5 IoT Discovery Kit (B-U585I-IOT02A)  that combines the MCU with a Wi-Fi® module, Bluetooth® module, and various sensors. Microsoft has chosen this kit as reference board for the new Azure Certified Device program. “The STM32U5 provides an excellent platform for delivering Azure IoT services via Azure RTOS leveraging the advanced features of STM32U5 microcontroller,” said Sam George, Corporate Vice President, Azure IoT at Microsoft Corporation. The kit will be available to order later in the year.
