The STM32H563 and STM32H573 microcontrollers extend the STM32 high performance portfolio. They offer enhanced performance and security, better power efficiency, and more embedded peripherals.

The STM32H563/573 product lines provide 1 to 2 Mbytes of flash memory, 640 Kbytes of SRAM. They come in 64- to 176-pin packages, including BGA, VFQFN68, WLCSP80, and LQFP profiles.

These lines are based on the Arm® Cortex®-M33 core with TrustZone® for Armv8-M, digital signal processing (DSP), and floating‐point unit (FPU) running up to 250 MHz with an optional extended ambient temperature range up to 125°C.

  • Performance:

    At 250 MHz, the STM32H563/573 MCUs deliver 375 DMIPS and a 1023 CoreMark performance score, executing from the flash memory, with 0-wait states using ST’s ART Accelerator.

    • Embedded peripherals
      • Up to 34 communication peripherals including:
      • I3C interface
