STMICROELECTRONICS STM32H573AII3Q ARM MCU, STM32 Family STM32H5 Series Microcontrollers, ARM Cortex-M33F, 32 bit, 250 MHz, 2 MB

STM32H573AII3Q is a high-performance microcontroller. It is based on the high-performance Arm® Cortex®-M33 32bit RISC core. It operates at a frequency of upto 250MHz. The Cortex®-M33 core features a single-precision floating-point unit (FPU), 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 memory protection unit (MPU) that enhances the application security. This device offers a security foundation compliant with the trusted-based security architecture (TBSA) requirements from Arm®. It embeds the necessary security features to implement a secure boot, secure data storage and secure firmware update. Besides these capabilities, the device incorporates a secure firmware installation feature, that allows the customer to secure the provisioning of the code during its production.
