　　STRFNFCA：NFC Transceiver IC

　　The STRFNFCA is an integrated transceiver IC for contactless applications.

　　The STRFNFCA manages frame coding and decoding in Reader, Card Emulation and Peer-to-Peer modes for standard applications such as near field communication (NFC), proximity and vicinity standards.

　　The STRFNFCA embeds an Analog Front End to provide the 13.56 MHz Air Interface.

　　The STRFNFCA supports ISO/IEC 14443 Type A and B in Reader and Card Emulation modes, ISO/IEC 15693 (single or double subcarrier in Reader mode only) and ISO/IEC 18092 protocols in Reader and Card Emulation modes.

　　The STRFNFCA also supports the detection, reading and writing of NFC Forum Type 1, 2, 3 and 4 tags.
