STMicroelectronics' introduces an architecture that reaches best-in-class ultra-low-power figures thanks to its high flexibility. STM32L4 MCUs have scored 153 in the standardized EEMBC™ ULPBench® tests that compare the efficiency of ultra-low-power MCUs. The STM32L4 series also shatters performance limits in the ultra-low-power world. It delivers 100 DMIPS based on its ARM® Cortex®-M4 core with FPU and ST ART Accelerator™ at 80 MHz.
