Hi Team,

 

we are using the STM32H753VI in our design.

we are not using the USB interfaces.

In this case, what is the termination to be done to the VDD33USB pin of STM whether it can be NC, GND?

 

Thanks

    Hello @Manikandan 

    My college @FBL has a very good FAQ on that: https://community.st.com/t5/stm32-mcus/faq-configuring-the-vdd50usb-and-vdd33usb-pins-on-stm32h7-when/ta-p/727887.

    It should be helpful.

    Best Regards.
