STMicroelectronics Circuitos integrados STMicroelectronics M24SR Dynamic NFC/RFID Tag

As Tag ICs NFC/RFID Dinâmica STMicroelectronics M24SR consistem em tag ICs NFC/RFID com interface dupla. Estes dispositivos incluem memória embutida EEPROM nas versões 2K, 4K, 16K e 64K. Eles podem ser operados de uma interface C I & SUP2, por um leitor RFID de 13,56 MHz ou um telefone NFC. A interface I²C consiste numa linha de dados bidirecional e uma linha de relógio e usa uma interface serial de dois fios. Eles se comportam como escravo no protocolo C I & SUP2. O protocolo RF é compatível com o Tipo A ISO/IEC 14443 e Tag Tipo 4 do NFC Forum.
