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 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. 1. Limited temperature range -25 to 85 °C SO8 (MN) UFDFPN8 (MC) TSSOP8 (DW) WFDFPN8 (MF) Wafer 2.
