STM32L4 series of ultra-low-power and performance MCUs
STM32L431, STM32L451 & STM32L471 devices extend the ultra-low-power portfolio and performance with an ARM® Cortex®-M4 core with DSP and floating-point unit (FPU) at 80 MHz.
- The STM32L431 portfolio offers from 128 Kbytes to 256 Kbytes of Flash and from 32-to 100-pin packages. Its memory range can easily be extended using SDIO & Quad-SPI interfaces.
- The STM32L451 portfolio offers from 256 Kbytes to 512 Kbytes of Flash and from 48-to 100-pin packages. Its memory range can easily be extended using SDIO & Quad-SPI interfaces.
- The STM32L471 portfolio offers from 512 Kbytes to 1 Mbyte of Flash and from 64- to 144-pin packages. Its memory range can easily be extended using SDIO, Quad-SPI and FSMC interfaces.

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.
MadeForSTM32™ is a new quality label delivered by ST, which is granted after an evaluation process. It helps engineers identify third party solutions with the highest level of integration and quality for the STM32 microcontrollers' ecosystem. MadeForSTM32™ is offered to members of the ST Partner Program who want to go one step further in our collaboration, with the overall objective of contributing to a high-quality STM32 ecosystem.
