STM32H5 Series

The STM32H5 series is based on the 32-bit Arm^® Cortex^®-M33 core running as high as 250 MHz. It offers the best combination of performance and security, in an affordable way.

Offering up to 2 Mbytes of flash memory in dual-bank memory, up to 640 Kbytes of SRAM and high peripheral integration, the STM32H5 series of microcontrollers offers developers from design freedom.

The STM32H5 portfolio offers large package options from 25- to 176-pin. It supports up to 125°C ambient temperature, making it suitable for harsh environments.

The STM32H5 provides a scalable security offer to address every need, including the security requirements of IoT devices. Developers can choose between several offers ranging from: the most essential security services to fully certified building blocks maintained by ST over the product lifecycle. This MCU series gives you more flexibility in your design choices.
