STM32U575XX Datasheet PDF - STMicroelectronics

Description
   The STM32U575xx devices belong to an ultra-low-power microcontrollers family (STM32U5 Series) based on the high-performance Arm® Cortex®-M33 32-bit RISC core. They operate at a frequency of up to 160 MHz.

   The Cortex®-M33 core features a single-precision FPU (floating-point unit), that supports all the Arm® single-precision data-processing instructions and all the data types.

   The Cortex®-M33 core also implements a full set of DSP (digital signal processing) instructions and a MPU (memory protection unit) that enhances the application security.

   The devices embed high-speed memories (up to 2 Mbytes of Flash memory and 786 Kbytes of SRAM), a FSMC (flexible external memory controller) for static memories (for devices with packages of 90 pins and more), two Octo-SPI Flash memory interfaces (at least one Quad-SPI available on all packages) and an extensive range of enhanced I/Os and peripherals connected to three APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.
