M24SR04-Y M24SR04-G Dynamic NFC/RFID tag IC with 4-Kbit EEPROM, NFC Forum Type 4 Tag and IC interface Datasheet - production data 7 bytes unique identifier (UID) 128 bits passwords protection Package TSSOP8 UFDFPN8 SO8 8-lead small-outline package (SO8) (DW) (MC) (MN) ECOPACK2 TSSOP8 ECOPACK2 UFDFPN8 ECOPACK2 Digital pad GPO: configurable General Purpose Output Wafer RF disable: activation/deactivation of RF commands Features Temperature range 2 I C interface From - 40 C up to 85 C 2 Two-wire I C serial interface supports 1 MHz protocol Description Single supply voltage: M24SR04 belongs to the ST25 family which 2.7 V to 5.5 V for grade Y includes all STMicroelectronics NFC/RFID tag and 2.4 V to 5.5 V for grade G (Limited reader products. temperature range -25 to 85 C) The M24SR04 devices is a dynamic NFC/RFID tag IC with a dual interface. It embeds an Contactless interface 2 EEPROM memory. It can be operated from an I C NFC Forum Type 4 Tag interface or by a 13.56 MHz RFID reader or an ISO/IEC 14443 Type A NFC phone. 106 Kbps data rate 2 The I C interface uses a two-wire serial interface, Internal tuning capacitance: 25 pF consisting of a bidirectional data line and a clock 2 line. It behaves as a slave in the I C protocol. Memory The RF protocol is compatible with ISO/IEC 512-byte (4-kbit) EEPROM 14443 Type A and NFC Forum Type 4 Tag.
