Description

M24SR64-Y belongs to the ST25 family which includes all STMicroelectronics NFC/RFID tag and reader products.

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.
