STMicroelectronics reveals advanced ultra-low-power STM32 microcontrollers for industrial, medical, smart-metering, and consumer applications

New flagship in ultra-low-power consumes less, delivers more at effective cost

Geneva, Switzerland, March 19, 2024 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has introduced a new generation of energy-conscious and cost-effective microcontrollers (MCUs) that can reduce energy consumption by up to 50% compared to previous product generations. This enables less frequent battery replacements, minimizes the impact of discarded batteries, and allows more designs to go battery free running solely from an energy-harvesting system such as a small photovoltaic cell.

In the global pursuit of sustainability, technologies deployed in smart buildings and Internet of Things (IoT) applications are critical tools for managing energy and resources efficiently. At the heart of the smart sensors and actuators making them possible, ST’s microcontrollers manage the processes that collect, filter, analyze, and act, communicating with high-level applications in the cloud. There are billions of these MCUs in action already and the expansion of smart living and working will demand billions more.

“It’s vital that these pervasive devices consume as little energy as possible as they help to minimize waste elsewhere. The new STM32U0 microcontroller series we are introducing today takes this notion to a new level, building on our proven ultra-low-power technologies,” explained Patrick Aidoune, General Purpose MCU Division General Manager, STMicroelectronics. “In fact, our new MCUs consume so little power that small devices in some dedicated applications like industrial sensor management can run for twice as long from the same size battery. This comes with the opportunity to add more advanced features and deliver cost-effective solutions for a variety of industrial, medical and consumer devices.”

The new STM32U0 MCUs enable this great leap in energy efficiency through a combination of their state-of-the-art design techniques and advanced manufacturing process. These include extremely low static power consumption in standby mode and superior wake-up performance, enabling the MCU to spend more time in power-saving sleep modes to minimize average energy demand.
