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.

Discover the large and pin-to-pin compatible STM32 ultra-low-power portfolio. This offer covers more than 2 billion of applications like IoT, Industrial sensors, wearables & home automation.
This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
Getting started with STM32L4
- Purchase a 32-pin, 64-pin or 144-pin Nucleo board, Discovery kit or Evaluation kit for STM32L4 MCUs.
Download the STM32CubeL4 embedded software package containing the HAL, LL (low-layer) APIs, and middleware. Then install ST’s STM32CubeMX graphical software configuration tool that supports pinout configuration, code generation and a power consumption calculator. Start with one of the many examples provided or build your own project.
