M24SR64-Y Dynamic NFC/RFID tag IC with 64-Kbit EEPROM, NFC Forum Type 4 Tag and IC interface Datasheet - production data Package 8-lead small-outline package (SO8) ECOPACK2 TSSOP8 ECOPACK2 UFDFPN8 TSSOP8 SO8 UFDFPN8 ECOPACK2 Digital pad GPO: configurable General Purpose Output RF disable: activation/deactivation of RF commands Wafer Temperature range 2 Features From - 40 C up to 105 C for I C operation From - 40 C up to 85 C for RF operation 2 I C interface 2 Two-wire I C serial interface supports Description 1 MHz protocol M24SR64-Y belongs to the ST25 family which Single supply voltage: 2.7 V to 5.5 V includes all STMicroelectronics NFC/RFID tag and reader products. Contactless interface The M24SR64-Y device is a dynamic NFC/RFID NFC Forum Type 4 Tag tag IC with a dual interface. It embeds an ISO/IEC 14443 Type A 2 EEPROM memory. It can be operated from an I C 106 Kbps data rate interface or by a 13.56 MHz RFID reader or an Internal tuning capacitance: 25 pF NFC phone. 2 The I C interface uses a two-wire serial interface, Memory consisting of a bidirectional data line and a clock 8-Kbyte (64-kbit) EEPROM 2 line. It behaves as a slave in the I C protocol. Support of NDEF data structure The RF protocol is compatible with ISO/IEC Data retention: 200 years 14443 Type A and NFC Forum Type 4 Tag.
