Overview
The ST95HF-VMD5T is an integrated transceiver IC designed for contactless applications by STMicroelectronics. This near field communication (NFC) transceiver manages frame coding and decoding in both Reader and Card Emulation modes, supporting various NFC, proximity, and vicinity standards. It embeds an Analog Front End (AFE) to provide a 13.56 MHz air interface, making it compatible with ISO/IEC 14443 Type A and B, ISO/IEC 15693, and ISO/IEC 18092 communication protocols. The ST95HF-VMD5T also supports the detection, reading, and writing of NFC Forum Type 1, 2, 3, and 4 tags, and is MIFARE® Classic compatible.
