The STM32H5E4 and STM32H5F4 microcontrollers extend the STM32 high performance portfolio and introduce new capabilities. They are the first STM32 MCUs based on Arm® Cortex®-M33 core, combining advanced graphics features, power efficiency, performance, and connectivity, while enhancing security without increasing cost.
This product line provides 3 to 4 Mbytes of flash memory, 1.5 Mbytes of SRAM, and package options from 100 to 176 pins in BGA and LQFP profiles.
The STM32H5F4 adds a dedicated encryption accelerator engine (AES, PKA, and OTFDEC), and ST-iRoT, and support for the STM32Trust TEE Secure Manager (delivered as X-CUBE-SEC-M-H5).
Both lines contain the Arm Cortex®-M33 core with TrustZone® for Armv8-M, DSP, and a floating‐point unit (FPU) running up to 250 MHz, with an optional extended ambient temperature range up to 105°C.
