STM32L552 and STM32L562 microcontrollers extend the STM32 ultra‐low‐power portfolio and performance with an Arm® Cortex®‐M33 processor core with TrustZone® for Armv8-M, DSP and floating‐point unit (FPU) at 110 MHz.
- The STM32L552 portfolio offers from 256 to 512 Kbytes of Flash memory and from 48 to 144-pin packages.
- The STM32L562 is available with 512 Kbytes of Flash memory and provides an additional encryption accelerator engine (AES, PKA, and OTFDEC).
All the packages are available with or without an embedded SMPS (DC/DC buck voltage regulator). Please refer to the data brief.
Featured Videos
As part of our embedded online event, we had the pleasure of filming with Reinhard Keil, a Senior Director of Embedded Tools at ARM.
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.
