M24SR02-Y Dynamic NFC/RFID tag IC with 2-Kbit EEPROM, NFC Forum Type 4 Tag and IC interface Datasheet - production data Package 8-lead small-outline package (SO8) ECOPACK2 TSSOP8 ECOPACK2 UFDFPN8 SO8 TSSOP8 UFDFPN8 ECOPACK2 Digital pad GPO: configurable general purpose output RF disable: activation/deactivation of RF commands Wafer Temperature range Features From - 40 C up to 85 C 2 I C interface Description 2 Two-wire I C serial interface supports M24SR02-Y belongs to the ST25 family, which 1 MHz protocol includes all STMicroelectronics NFC/RFID tag Single supply voltage: 2.7 V to 5.5 V and reader products. Contactless interface The M24SR02-Y device is a dynamic NFC/RFID tag IC with a dual interface embedding an NFC Forum Type 4 Tag 2 EEPROM. It can be operated from an I C ISO/IEC 14443 Type A interface or by a 13.56 MHz RFID reader or from 106 Kbps data rate an NFC phone. Internal tuning capacitance: 25 pF 2 The I C interface uses a two-wire serial interface, consisting of a bidirectional data line and a clock Memory 2 line. It behaves as a slave in the I C protocol. 256-byte (2-kbit) EEPROM The RF protocol is compatible with ISO/IEC Support of NDEF data structure 14443 Type A and NFC Forum Type 4 Tag.
