STM32H5 Series

Thumbnail STM32H5 MCU introduction

Performance and security: the best of both worlds

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 option 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.
