Help urgently in NFC project

[Eng_SAME7]

Hi all, hope you are doing well,

I'm doing an NFC Project (Card reader with ATMega16) but I have a problem with choosing the better NFC chip..

PN5331B3HN or TRF7970A ??

I know that TRF7970A supports many NFC protocols and used in a lot of applications...

but I need some one to assure me that with the reason y is that better ?

thanks
SAM

The TRF7970A is an integrated analog front end and data-framing device for a 13.56-MHz RFID/Near Field Communication system. Built-in programming options make it suitable for a wide range of applications for proximity and vicinity identification systems.
It can perform in one of three modes: RFID/NFC Reader, NFC Peer, or in Card Emulation mode. Built-in user-configurable programming options make it suitable for a wide range of applications.
The TRF7970A is configured by selecting the desired protocol in the control registers. Direct access to all control registers allows fine tuning of various reader parameters as needed.
