Texas Instruments TRF7970A Transceiver IC

Texas Instruments TRF7970A Transceiver IC is an integrated analog front end and data-framing device for a 13.56MHz RFID and Near Field Communication system. Built-in programming options make this TI device suitable for a wide range of applications for proximity and vicinity identification systems. It can perform in one of three modes: RFID and NFC Reader, NFC Peer, or Card Emulation. 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.
