    The STM32U595 and STM32U5A5 microcontrollers extend the STM32 ultra-low-power portfolio. They offer enhanced performance thanks to:
  • an Arm® Cortex®-M33 processor core running at 160 MHz with TrustZone® for Armv8-M
  • digital signal processing (DSP)
  • a floating-point unit (FPU)

Built on an ultra-low power platform, the STM32U595/U5A5 MCUs provide a high level of integration.

  • The STM32U595 MCUs offer from 2 to 4 Mbytes of flash memory.
  • An additional encryption accelerator engine is also included (AES, PKA, and OTFDEC) for the STM32U5A5 MCUs.

The STM32U595/U5A5 MCUs are the first of the STM32 family to provide 4 Mbytes of flash memory.
They are available in 64- to 169-pin packages.
