ST’s latest ultra-efficient microcontrollers are ideal to be the central controller in a full range of applications like fitness bands, smart watches, small medical equipment, smart meters and smart industrial sensors − requiring instant responses and minimal downtime for battery charging.

The new STM32L4+ series MCUs offer more performance (up to 120 MHz), more embedded memory (up to 2 Mbytes of Flash memory and 640 Kbytes of SRAM) and richer graphics and connectivity features while keeping the best‐in‐class ultra‐low‐power capability.

As claimed by ST, the STM32L4+ series stretch performance limits in the ultra‐low‐power world by delivering 150 DMIPS/405 CoreMark score while executing from internal Flash memory and by embedding 640 Kbytes SRAM enabling more advanced consumer, medical and industrial low-power applications and devices.

An integrated ‘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, according to ST. In addition, an innovative on-chip Chrom-ART Accelerator enhances graphics performance.

The STM32L4+ series is supported by an extensive 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 (IDEs) as part of the ST Partner Program.

Applications developed for the earlier STM32L4 microcontrollers can run unchanged on the new devices, with improved performance, stated ST in the Press release.

The STM32L4+ devices are in production now, in various package options. Pricing starts at $6.52 for orders of 10,000 pieces.
