STM32L4 series of ultra-low-power MCUs
ST has built a new architecture to reach best-in-class ultra-low-power figures thanks to its high flexibility. STM32L4 MCUs have scored 447 ULPMark-CP and 167 ULPMark-PP in the standardized EEMBC™ ULPMark® tests that compare the efficiency of ultra-low-power microcontrollers. Moreover, the STM32L4 series 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.
STM32L4 microcontrollers offer dynamic voltage scaling to balance power consumption with processing demand, low-power peripherals (LP UART, LP timers) available in Stop mode, safety and security features, smart and numerous peripherals, advanced and low-power analog peripherals such as op amps, comparators, LCD, 12-bit DACs and 16-bit ADCs (hardware oversampling).
The series are available in different lines: STM32L4x1 (Access line), STM32L4x2 (USB Device), STM32L4x3 (USB Device, LCD), STM32L4x5 (USB OTG) and STM32L4x6 (USB OTG, LCD).
To simplify migration and give you all the flexibility you need, the STM32L4 is pin-to-pin compatible with the different STM32 series and opens the door to the full STM32 ecosystem.
