M24SR64-YDW6T/2

NFC/RFID TAG, 8KB, 13.56MHZ, TSSOP-8.

The M24SR64-YDW6T/2 is a dynamic NFC/RFID Tag IC with 64kb EEPROM, NFC forum type-4 tag and I?C interface. 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 bi-directional data line and a clock line. It behaves as a slave in the I?C protocol and the RF protocol is compatible with ISO/IEC 14443 type-A and NFC forum type-4 tag. 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.
