描述 Description

The ST25R95 is an integrated transceiver IC for contactless applications.

The ST25R95 manages frame coding and decoding in Reader and card emulation modes for standard applications such as near field communication (NFC), proximity and vicinity standards.

The ST25R95 supports ISO/IEC 14443 Type A communication in reader and card emulation modes, and ISO/IEC 14443 Type B, ISO/IEC15693, and FeliCa in reader mode.The ST25R95 embeds an analog front end to provide the 13.56 MHz air interface.

The ST25R95 also supports the detection, reading and writing of NFC Forum Type 1, 2, 3, 4, and 5 tags, and an SPI interface to communicate with the host controller.
