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.

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

Yes.

[SGasp.1]

can you share the link for doing the comparison thanks ?

Using STM32CubeMX tool, through "Cross selector" feature.

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