Are LQFP STM32H750, STM32H753 and STM32H755 pin compatible?

[LMI2]

Are all all H75* CPUs pin compatible. I would like to use LQFP STM32H750, but there is none stocked. Digikey has some H755 and H753 stocked. Can I use them, or what ever H75* CPUs Digikey happens to have when I'm ready.

Hello @LMI2​ ,

STM32H750 and STM32H753 (LQFP packages) are pins compatible.

STM32H755 (LQFP) is not compatible with STM32H753 and STM32H750.

I advise you to have a look at the pins descriptions in the products Datasheets for more details.

You can use CubeMX to select the list of the MCUs which are compatible and compare the pins, through "List Pinout Compatible MCUs" feature.

Please refer to the UM1718 in Tutorial 5 "Exporting current project configuration to a compatible MCU", for more details on how to use this feature.

In addition you can use the ST-MCU-FINDER tool (integrated also in STM32CubeMX) to compare the characteristics of two or more MCUs through the "Cross Selector" tab.

Hope my answer helped you! :smiling_face_with_smiling_eyes:

Thank you. That was a good and full answer

That menu item "List pinout compatible MCUs" was in different place than I thought, but I found it anyway.
