TRF7962A - Texas Instruments

TRF7962A Fully Integrated 13.56-MHz RFID Reader/Writer IC

The TRF7962A device is an integrated analog front-end (AFE) and data-framing device for a 13.56-MHz RFID reader/writer system that supports ISO/IEC 15693. Built-in programming options make it suitable for a wide range of applications for proximity and vicinity identification systems. The reader is configured by selecting the desired protocol in the control.
