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. It reaches 375 DMIPS and a 1023 CoreMark score.

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.

Optimized cost/performance trade-off

Leveraging ST’s non-volatile-memory 40nm technology, the STM32H5 comes with a large choice of memory, peripherals, and package options (25-176 pins).
