CR95HF
13.56 MHz multi-protocol contactless transceiver IC with SPI and UART serial access-
Active
The CR95HF is an integrated transceiver IC for contactless applications.
The CR95HF manages frame coding and decoding in Reader mode for standard applications such as near field communication (NFC), proximity and vicinity standards.
The CR95HF embeds an Analog Front End to provide the 13.56 MHz Air Interface.
The CR95HF supports ISO/IEC 14443 Type A and B, ISO/IEC 15693 (single or double subcarrier) and ISO/IEC 18092 protocols.
The CR95HF also supports the detection, reading and writing of NFC Forum Type 1, 2, 3 and 4 tags.
