Hi,

We are planning to use STM32H753xI in our design. We should prepare Architectural Block diagram of the Board. To do that we need to know the Pin multiplexing details of the device and accordingly plan the Interfaces in the architecture. Can you please provide the Pin multiplexing details in the form of Excel sheet or any software through which we can easily select one of  the Options out of the available Multiplexing.

Regads,

Vijetha

I believe CubeMX provides some control and documentation output.

If not you'll need to type the stuff in the old fashion way, or get a minion to do it. This also has the added benefit of crossing a number of neurons/synapses and providing you some knowledge instead of the robot.

Hi

hn.vijetha

‌,

Pins multiplexing is available in the datasheet of the product you selected,

http://www.st.com/resource/en/datasheet/stm32h753xi.pdf

related one in your case.

Otherwise, you should be able to have this multiplexing in a .csv file that you get using STM32CubeMX:

1. Open a new project to use STM32H753XI device you select from the STM32CubeMX interface
2. Go to ''Pinout'' tab, and then select ''Generate CSV pinout text file'' as following:

Hi,

Is this STM32CubeMX software available as Evaluation version or we need to buy license? I want it just to check Pin Multiplexing and select the interfaces accordingly.

Regards,

And If we have to do it manually from the datasheet, then are you referring to Table 8 ?

Hi,

Thank you, I am able to get CSV file. Is it possible to sort out the pin outs as per Interfaces using the tool?

Regards,

What do you mean by 'sort per interface'? Pins for each peripheral you mean?

In the datasheet, you have table 8 for the pinout and tables from 9 to 19 for the alternate functions.
