STMicroelectronics STM32H7x3 MCUs

The STM32H743/753 lines offer the performance of the Cortex-M7 core running up to 400 MHz. Combined with a smart architecture based on a multipower domain, developers can always use the best configuration to optimize data transfers and CPU load while staying gentle on the power budget when needed.

The embedded hardware accelerators and the extensive digital and analog peripheral set make the STM32H743/753 very well suited for industrial applications where fast reaction time is key or HMI applications where the graphic and audio support will allow an unprecedented user experience with an embedded microcontroller.
