STMicroelectronics reveals STM32U3 microcontrollers extending ultra-low power innovation for remote, smart and sustainable applications

STMicroelectronics has introduced new STM32U3 microcontrollers (MCUs) with 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 that depend on the lowest possible power consumption include utility meters, healthcare devices such as glucose meters and insulin pumps, animal care monitors, forest-fire sensors, and industrial sensors including thermostats and smoke detectors. STM32U3 MCUs are also used in consumer products such as smart watches, wearables, and hearables.

“The STM32U3 series builds on the heritage of ST-established ultra-low-power general-purpose microcontroller class as it is known today, which opened the door to widespread diffusion of smart technology in diverse environments,” commented Patrick Aidoune, General-Purpose MCU Division General Manager, STMicroelectronics. “Leveraging innovative techniques such as recent advancements in ...
