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.
One lead customer, in the security-systems market, is using the
STM32U0 in security cameras to wake the device when motion is
detected and thus enhance surveillance while saving energy. Another
has created ultra-long-lasting smoke detectors, while a further
application, by Ascoel, is using the STM32U0 to manage
power-conscious functions of a water meter.
“Ascoel builds a wide range of innovative electronic devices
with a focus on IoT technologies. We are working to design an
ultrasonic water meter, with battery lasting for more than 10
years, integrating an LCD screen for real-time data, as well as the
necessary security,” said Francesco Cerretani, Senior Software
Developer, Ascoel. “We found that the STM32U0 was the perfect
solution, supporting our goal to create a low-cost,
ultra-low-power, easy-to-install, zero maintenance, precise water
meter. When deployed at scale in the customer’s grid, it will
improve control over water leakage and contribute to reducing the
environmental impact.”
The STM32U0 enhances cost-effectiveness by providing an LCD
segment display controller. Devices with an LCD, like Ascoel’s
water meter as well as thermostats, smart retail labels,
access-control panels, and factory automation can take advantage of
this to reduce the cost of their PCB. Additional value-added
features of STM32U0 MCUs include numerous analog peripherals like
analog-to-digital converters (ADC), digital-to-analog converters
(DAC), operational amplifiers, and comparators. There is also an
on-chip system oscillator that helps cut the bill of materials to
save costs and PCB space.
STM32U0 devices are the first MCUs running on Arm® Cortex®-M0+
targeting SESIP Level 3 and PSA level 1 focusing on firmware code
protection. Certification provides an independent assurance of the
STM32U0 security capabilities that product manufacturers can
leverage to comply with the coming voluntary US Cyber Trust Mark
and mandatory EU Radio Equipment Directive (RED).
Developers can also take advantage of up to 256KB of Flash,
package options up to 81 pins, and 56MHz core speed, which are
generous specifications for this class of device.
The STM32U0 series is in production now and ST is making the new
devices available at an attractive price point starting at $0.68
for 1,000 units. Sample requests and further pricing options are
available from local ST sales offices.
