STMICROELECTRONICS STM32H523ZET6 ARM MCU, STM32 Family STM32H5 Series STM32H523xx Group Microcontrollers, ARM Cortex-M33F, 32 bit

STM32H523ZET6 is a STM32H5 series, high-performance microcontroller based on the high-performance Arm® Cortex®-M33 32-bit RISC core. It operates at a frequency of up to 250MHz. The Cortex®-M33 core features a single-precision floating-point unit (FPU), which supports all the Arm® single-precision data-processing instructions and all the data types. The Cortex®-M33 core 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®. Besides these capabilities, this device incorporates a secure firmware installation that allows the customer to secure the provisioning of the code during its production. A flexible life cycle is managed thanks to multiple levels of protection and secure debug authentication.
