Serving as a central controller in applications such as smartwatches and smart meters

STMicroelectronics has launched a new ultra-low power microcontroller that makes everyday smart electronic devices easier to use and extends battery life.

This new STM32L4+ device, a product of the STM32L4 series, has improved performance up to 120 MHz and 150 DMIPS (233 ULPMark-CP), and can serve as a central controller in applications such as all kinds of fitness bands, smartwatches, small medical devices, smart meters, and smart industrial sensors.

The STM32L4+ is equipped with the features targeted for application design. It offers powerful processor performance with the largest on-chip memory for such ultra-low-power microcontrollers, along with state-of-the-art graphics performance for a smooth and flexible user experience.

This new Chrom-GRC™ graphics controller can adjust circular displays (TFT-LCDs) as efficiently as square displays without wasting resources on managing unnecessary display pixels. In addition, ST’s innovative Chrom-ART Accelerator™ with enhanced graphics performance is provided on-chip.

“We all want smart products to seamlessly integrate into our daily lives, satisfy our needs, and require minimal attention,” said Michel Buffa, Head of Microcontroller Business at ST. “Because the STM32L4+ microcontroller series provides the industry’s largest controller memory capacity and highest-efficiency graphics performance, it will be possible to realize new smart products with more differentiated features and seamless interactions.”

Using the STM32L4+ series allows for extensive use of the proven STM32 development ecosystem, simplifying designs and minimizing time-to-market. This ecosystem provides affordable prototyping boards, software examples, free tools, and high-quality software, hardware, and integrated development environments (IDEs) from partners as part of the ST Partner Program. Applications developed based on existing STM32L4 microcontrollers can operate on the new devices with enhanced performance without modification.
