STM32F746NGH6 can we directly replace by STM32F779NIH6 or STM32F777NIH6

[JK1234]

Hello Team,

Currently we are using STM32F746NGH6 MCU. But we want 2Mb flash memory in same series. But in same series there is 2Mb flash memory is not available.

So, we are checking about STM32F779NIH6 or STM32F777NIH6. Can we directly replace STM32F746NG by STM32F779NIH6 or STM32F777NIH6. Is it pin to pin compatible?

Please provide your valuable inputs.

Thanks & Regards,

Hello @JK1234 and welcome to the ST Community 😊.

If you are looking to find what MCUs are compatible with your's, you can use CubeMX. CubeMX will list pin-compatible parts. All you have to do is to create a project based on your chip, configure it if you want, then go to Pinout -> List Pinout Compatible MCUs.

Best Regards.

Hello @STTwo-32,

I am not familiar with CubeMX tool.

So, please help me to check about Can we directly replace STM32F746NGH6 by STM32F779NIH6 or STM32F777NIH6. Is it pin to pin compatible? 

If is it pin to pin compatible, please suggest EVAL board information also.

I hope I will get my answer 

Thanks,

Hello @STTwo-32 ,

I checked in CubeMX tool.

Tool suggest compatible MCU is STM32F779NIH6 against STM32F746NGH6.

But if, I compared both datasheets then I found there is a pin type is change.

refer below capture

So, please provide your inputs.

Thanks,

STM32F779NIH6 is not due to the DSI pins. CubeMX shouldn't be telling you they're compatible here.

STM32F777NIH6 looks to be pin to pin compatible.

Hello @TDK ,

Thanks for updates.

If STM32F777NIH6 looks to be pin to pin compatible. 

Can please suggest Evaluation board for the STM32F777NIH6.

Thanks,

There is no eval board for STM32F777NIH6.

From STM32CubeMX, here are your options for ST boards for STM32F7 chips:

Hello,

These are the available boards for STM32F7 series (excluding Nucleo boards)

There is no Eval board for this exact part number STM32F777NIH6.

The nearest part number is STM32F779NIH6 which has an Eval board: https://www.st.com/en/evaluation-tools/stm32f779i-eval.html
