Change of microcontroller between STM32F746ZGT6 and STM32F756ZGT6

[SGasp.1]

Hi everyone .... due to the problem of the getting the components.. I would like to understand in your opinion which is the difference between STM32F746ZGT6 and STM32F756ZGT6..

Can I port the code easily ?

Which changes I should do ?

Thanks

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.

 

Hope that I've answered your question.

Using STM32CubeMX tool, through "Cross selector" feature.

For more detail, please refer to the "4.2.4 Cross selector" section in the UM1718.

Basically I can directly flash the prevous project .hex done with STM32Cube inside the new microcontroller?

Yes.
