STM32L4+ Series Microcontrollers

STMicroelectronics' STM32L4+ devices, a new generation of the STM32L4 series, stretch performance to 150 DMIPS (233 ULPMark™-CP) at 120 MHz and 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 of these applications require sophisticated functions, instant responses, and minimal downtime for battery charging, making the ultra-efficient STM32L4+ an ideal fit.

The 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.
