ST: next-gen smart objects can do more and consume less with new STM32L4+ MCUs

The smart electronic objects people interact with every day can be easier to use and run for longer on batteries when designed around the latest ultra-low-power microcontrollers from STMicroelectronics.

The new STM32L4+ devices – a new generation of the STM32L4 series that stretches performance to 150DMIPS (233 ULPMark-CP) at 120MHz – can act as the central controller in a full range of fitness bands, smart watches, small medical equipment, smart meters, smart industrial sensors and more. All these applications require sophisticated functions, instant responses, and minimal downtime for battery charging, making the ultra-efficient STM32L4+ an ideal fit.

STM32L4+ gives application designers the features they need to achieve these goals: strong processor performance with the largest on-chip memory for this type of ultra-low-power microcontroller, and the most advanced graphics capabilities for smooth and fluid user experiences. The new Chrom-GRC graphics controller can handle circular displays (TFT-LCDs) just as efficiently as square ones, without wasting resources managing pixels that are never displayed. Also on-chip is ST’s innovative Chrom-ART Accelerator, which enhances graphics performance.

Designers using the STM32L4+ series can use the extensive – and well proven – STM32 development ecosystem, which helps streamline design and minimize time to market. The ecosystem provides affordable prototyping boards, software examples, free tools, and high-quality third-party software, hardware, and integrated development environments as part of the ST Partner Program. Applications developed for the earlier STM32L4 microcontrollers can run unchanged on the new devices, with improved performance.
