STM32U575 and STM32U585 microcontrollers extend the STM32 ultra‐low‐power portfolio and offer enhanced performance thanks to an Arm® Cortex®‐M33 processor core with TrustZone® for Armv8-M, DSP and floating‐point unit (FPU) running at 160 MHz.
The STM32U575 portfolio offers from 1 to 2 Mbytes of Flash memory and from 48- to 169-pin packages.
The STM32U585 is available with 2 Mybtes 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.
