PN7412 how to connect n.c. pins

Hello,

We are using PN7412 in our application. It belongs to the PN7462 family but it doesn't have contactless functionalities.

It has 5 n.c. pins which don't have clear connection instructions. In pinout table-4 of the datasheet (page 15/114) it is said to "See UM10858 for connection details". The pins that are n.c. are RXN, RXP, VMID, ANT1 and ANT2. 

The problem is when we look at UM10858, there are no instructions what to do with these n.c. pins when they are not used, which is the case with PN7412.

Can anybody point me to these connection instructions please. Should these pins be left open or something different? Thank you in advance!

Regards,

Vulinovic Nikola

Thank you for submitting this question. My apologies for the delayed response.

As indicated in the documentation, these are not connected pins don't have any circuit functionality, so these pins can be left out floating.

Best Regards,
Fabian
