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 company reported.
 
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.
 
STM32L4+ offers strong processor performance with the largest on-chip memory for this type of ultra-low-power microcontroller, and 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 Chrom-ART Accelerator, which enhances graphics performance.
 
ST has shipped more than three billion of its advanced STM32 microcontrollers, which are used in high-tech products from the smallest sensors and implantable medical devices to consumer gadgets, white goods, power tools, media devices, communications, computing and industrial control.
 
The STM32L4+ is the latest in this wide-ranging STM32 family. “L” stands for ST’s ultra-low-power design features and modes, which combine to ensure the chip always consumes the least possible energy. “4” describes the high-performing Arm Cortex-M core. And “+” signifies more compute performance, more memory, more features on-chip, and more efficient, high-performing graphics for the latest product designs.
