The STM32F756 has crypto/hash features, but is otherwise identical to the STM32F746. The code should run on it without modification.

Hello @SGasp.1​ ,

There is no big difference between STM32F746ZGT6 and STM32F756ZGT6 (adding security features for F756).

(Please refer to the attached Excel file to check the comparison between the IP/parameters of the products)

The STM32F756xx devices are fully pin-to-pin, compatible with the STM32F74xxx devices and share the same power supplies.

You can refer to the datasheet for more clarification about your product.
