"NC" pins on ST25R95-VMD5 Not Connected or Do Not Connect?

[Casper van Doorne]

Hi Everyone,

I'm designing an application with the ST25R95. It has several pins that are labeled as "NC".

To improve the PCBA lay-out, particularly the GND plane under the IC, I want to connect as many as possible pins to GND.

My Question:

Can the "NC" pins of the ST25R95 be tied to GND (Not Connected pins) or should I leave these pins floating (Do Not Connect pins) ?

Thanks in advance for sharing your insights.

Hi,

on the X-NUCLEO-NFC03A1 board, the NC pins 3/4/7/10/11/23-28 are connected to GND. See schematics in UM2479.

Same for the CR95HF transceiver board in the M24LR-DISCOVERY kit.

Well Brian, I guess that answers my question.

Thank you very much for your contribution!
