We are currently doing a design with STM32H725REV. What should we do with the exposed pad in the middle of the package. Connect to ground or floating or?

Hi @niels​ ,

I confirm that the exposed pad has to be connected to the ground.

This is applicable for VFQFPN package of STM32H725/H735 products. Datasheets will be updated to precise this.

Hi @niels​,

I'm taking the action to check how to connect exactly the exposed pad on the VFQFPN package. I'll come back to you on this regard.
