STM32H5 MCU series

Most powerful Arm® Cortex®-M33 MCU


STM32H5 simplifies the design of secure industrial applications

Most powerful Arm® Cortex®-M33 MCU yet

The STM32H5 MCU series is the industry’s first 32-bit MCU with an Arm® Cortex®-M33 core running as high as 250 MHz. Leveraging ST’s Non-Volatile-Memory (NVM) 40nm technology, STM32H5 reaches 375 DMIPS and a 1023 CoreMark score, executing from the embedded flash memory.

Strong, scalable security to address every need

Developers can choose between different security offers, from the most essential building blocks to fully certified services maintained by ST over the product lifetime. The STM32H5 is the first MCU with a trusted execution environment solution: STM32Trust TEE Secure Manager.

Optimized cost/performance trade-off

The industrial-grade STM32H5 offers a large choice of memory, peripherals, and package options (from 25 to 176 pins) and supports up to 125°C ambient temperature.
