STMicroelectronics’ STM32L4 series microcontrollers introduce peripheral and package configurations that simplify design and increase flexibility.

According to the EEMBC ULPBench tests for low-power microcontrollers, the devices achieve 176.70 ULPMark-CP without the help of a buck converter. The EEMBC CoreMark score of 273.55 at 80 MHz shows that the series delivers a combination of high peak performance and energy efficiency.

The product’s performance and efficiency advantages come from smart architectural features such as independently adjustable peripheral supply voltages and a programmable multispeed internal clock, as well as Batch Acquisition Mode (BAM) and ST’s Adaptive Real-Time Accelerator (ART Accelerator). Multiple power management modes, including ultralow-power 8 nA shutdown, help maximise energy savings.

The series enhances choice and flexibility for designers who need to secure smart connected Internet of Things (IoT) devices, such as wearables or home automation controllers, or need versatile peripherals and connectivity for industrial or medical devices. The series is suitable for smart meters, benefiting from the wide temperature range and high on-chip memory density to achieve a robust single-chip solution.
