1.3 Description

The TRF7970ARHBR 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.
