STMicroelectronics CI tag NFC/RFID M24SR Dynamic STMicroelectronics

I CI tag NFC/RFID M24SR Dynamic STMicroelectronics sono CI tag NFC/RFID dinamici con doppia interfaccia. Questi dispositivi comprendono una memoria EEPROM integrata in versioni da 2 K, 4 K, 16 K e 64 K. Possono essere operati da un'interfaccia I²C o tramite un lettore RFID a 13,56 MHz o un telefono NFC. L'interfaccia I²C usa due interfacce seriali a due fili composte da una linea di dati bidirezionale e una linea di clock. Si comportano come uno slave nel protocollo I²C. Il protocollo RF è compatibile con tag ISO/IEC 14443 di tipo A e NFC Forum di tipo 4.
