Description
M24SR04 belongs to the ST25 family which includes all STMicroelectronics NFC/RFID tag and reader products.
The M24SR04 devices 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. It behave...
