M24SR02-YMN6T/2 (STMICROELECTRONICS)

The M24SR02-YMN6T/2 is a dynamic NFC/RFID Tag IC with a dual interface and it embeds an 2kb EEPROM memory. It can be operated from an I?C interface or by a 13.56MHz RFID reader or an NFC phone. The I?C interface uses a 2-wire serial interface, consisting of a bidirectional data line and a clock line. It behaves as a slave in the I?C protocol. The RF protocol is compatible with ISO/IEC 14443 type-A and NFC forum type-4 tag. The dynamic NFC/RFID tag can be accessed either from the I?C or the RF interface. The RF and I?C host can read or write to the same memory that is why only one host can communicate at a time with the IC. The management of the interface selection is controlled by the IC device itself.
