STM32U5 MCUs address power saving issues

STMicroelectronics has unveiled a new generation of extreme power-saving microcontrollers (MCUs), the STM32U5 series.

This new generation has been designed to meet the most demanding power/performance requirements for smart applications including wearables, personal medical devices, home automation, and industrial sensors.

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

The new STM32U5 series teams the efficient Arm Cortex-M33 core with ST’s proprietary power-saving features and on-chip IP cutting down energy demand while looking to boost performance. The line also adds state-of-the-art features that are needed by modern 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 almost doubled its share of global microcontroller sales in the last five years, shipping more than two billion ultra-low-power STM32 devices to date. We are particularly strong in the ultra-low-power category with about 25% of that market,” said Ricardo de Sa Earp, Group Vice President, Microcontroller Division General Manager, STMicroelectronics. “We expect our STM32U5 microcontrollers to be even more popular, enabling our customers to create new smart consumer and industrial products that deliver superior energy rating, performance, and cyberprotection.”

ST has also created the STM32U5 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.
