Dear all,

Could you teach me about NC pin connection?

What is the reason why you recommend to connect to ground?

I think that I can make NC pin as floating.

However you say that 'Connect to ground' at Pin function of data sheet.

Does the floating have negative impact on somewhere?

Dear Takao,

I agree with you that NC typically denotes a "no connection," but they have it referenced as a connection to ground. Let me reach out to the designer and see if I can gather some information for you.

Dear Takao,

the pin in question is not connected physically internal to the IC, so you should be able to leave it floating if you choose. As it is a potential aerial on the package, we recommend through the datasheet that it be grounded. Let me know if you have any other questions
