Hi TI-team

My customer have question.

Pin 2, 7 are NC.

In EVM, it is connected to GND.

Can these be used without being connected (OPEN)?

What is the problem if it is not connected to GND?

Best Regards,

HI Hayashi-san,

NC means they are not internally connected. The EVM has them connected to GND as this simplifies the layout. There is no impact by leaving these floating.

I hope this answers your question.
