STMicroelectronics STM32H5F4ZJ→STM32H5F4ZJJ6

The STM32H5Fxxx devices are high-performance microcontrollers of the STM32H5 series, based on the high-performance Arm^® Cortex^®-M33 32-bit RISC core. They operate at a frequency of up to 250 MHz. 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. This core implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security.

The devices embed high-speed memories (up to 4 Mbytes of dual bank flash memory and 1536 Kbytes of SRAM), a flexible external memory controller (FMC) for devices with packages of 100 pins and more, two OCTOSPI memory interfaces, 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. The devices offer security foundation compliant with the trusted-based security architecture (TBSA) requirements from Arm^®. They embed the necessary security features to implement a secure boot, secure data storage and secure firmware update. Besides these capabilities, the devices incorporate a secure firmware installation that allows the customer to secure the provisioning of the code during its production.
