STM32L471RET6 ARM-Cortex®-M4 microcontroller, 32bit, 1.7V, 512KB,LQFP-64

ST has developed a new architecture to achieve the best levels of ultra-low power thanks to its high flexibility. STM32L4 MCUs have achieved 447 ULPMark-CP and 167 ULPMark-PP in standardized EEMBC™ ULPMark® tests, which compare the efficiency of ultra-low power microcontrollers. In addition, the STM32L4 series breaks the performance limits in the world of ultra-low-power microcontrollers. It delivers 100 DMIPS based on its Arm® Cortex®-M4 core with FPU and ST ART Accelerator™ at 80 MHz.

The STM32L4 microcontrollers offer dynamic voltage scaling to balance power consumption with processing needs, low power peripherals (LP UART, LP timers) available in stop mode, security features, intelligent and numerous peripherals, advanced low power analog peripherals such as op amplifiers, comparators, LCD, 12-bit DACs and 16-bit hardware oversampling (ADCs).
