How Should the Schematic Be Configured If USB Is Not Used on the nRF54LM20?

[noseed]

Hello,

We are planning to use the nRF54LM20A, but we do not intend to implement USB in our design.

For the nRF52 series, the datasheet provides a reference schematic for configurations without USB.

However, we could not find similar guidance for the nRF54LM20A.

In particular, we are unsure how to handle newly added pins such as TXRTUNE when USB is not used.

Could you please provide guidance or a recommended schematic for handling the USB-related pins when USB is not implemented?

Thank you in advance.

Hi, 

You can leave all the USB pin floating. 

Example here on how it would look with all USB related pins floating.
