ST公司的M24SR64－Y是具有双接口的动态NFC－RFID标签IC,嵌入EEPROM存储器,RF协议和ISO/IEC 14443 Type A 与NFC Forum Type 4标签兼容,能与13.56 MHz RFID阅读器或NFC手机工作.本文介绍了M24SR64－Y主要特性,框图以及评估板M24SR－DISCOVERY主要特性,框图,电路图,材料清单和PCB元件布局图.

The M24SR64-Y device is a dynamic NFC/RFID tag IC with a dual interface. It embeds an EEPROM memory. It can be operated from an I2C interface or by a 13.56 MHz RFID reader or an NFC phone.

The I2C interface uses a two-wire serial interface, consisting of a bidirectional data line and a clock line. It behaves as a slave in the I2C protocol.

The RF protocol is compatible with ISO/IEC 14443 Type A and NFC Forum Type 4 Tag.
