The CR95HF from STMicroelectronics is a Multi-Protocol Contactless Transceiver IC that operates at 13.56 MHz. It supports read-and-write operating modes and features a highly integrated Analog Front End (AFE) for RF communications. This IC includes a dedicated internal frame controller and manages frame coding and decoding in Reader mode for standard applications such as near-field communication (NFC), proximity, and vicinity standards. It supports ISO/IEC 14443 Type A and B, ISO/IEC 15693 (single or double subcarrier), and ISO/IEC 18092 communication protocols along with MIFARE® Classic compatibility. The IC also supports the detection, reading, and writing of NFC Forum Type 1, 2, 3, and 4 tags. It is available in a 32-lead VFQFPN package that measures 5 x 5 mm and includes SPI and UART serial access interfaces.
