M24SR02-YMF7T/2 Datasheet

Dynamic NFC/RFID tag IC with 2-Kbit EEPROM, NFC Forum Type 4 Tag and I²C interface


M24SR02-Y belongs to the ST25 family which includes all STMicroelectronics NFC/RFID tag and reader products.
The M24SR02-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.
