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.
