M24SR16-Y Dynamic NFC/RFID tag IC with 16-Kbit EEPROM, NFC Forum Type 4 Tag and IC interface Datasheet - production data Digital pad GPO: configurable General Purpose Output RF disable: activation/deactivation of RF commands UFDFPN8 TSSOP8 SO8 (MC) Temperature range (DW) (MN) From - 40 C up to 85 C Features Description 2 M24SR16-Y belongs to the ST25 family which I C interface includes all STMicroelectronics NFC/RFID tag and 2 Two-wire I C serial interface supports reader products. 1 MHz protocol The M24SR16-Y device is a dynamic NFC/RFID Single supply voltage: 2.7 V to 5.5 V tag IC with a dual interface. It embeds an 2 EEPROM memory. It can be operated from an I C Contactless interface interface or by a 13.56 MHz RFID reader or an NFC Forum Type 4 Tag NFC phone. ISO/IEC 14443 Type A 2 The I C interface uses a two-wire serial interface, 106 Kbps data rate consisting of a bidirectional data line and a clock 2 Internal tuning capacitance: 25 pF line. It behaves as a slave in the I C protocol. The RF protocol is compatible with ISO/IEC Memory 14443 Type A and NFC Forum Type 4 Tag. 2-Kbyte (16-kbit) EEPROM Support of NDEF data structure Data retention: 200 years Write cycle endurance: 1 million Write cycles at 25 C 600k Write cycles at 85 C Read up to 246 bytes in a single command Write up to 246 bytes in a single command 7 bytes unique identifier (UID) 128 bits passwords protection Package 8-lead small-outline package (SO8) ECOPACK2 TSSOP8 ECOPACK2 UFDFPN8 ECOPACK2 October 2017 DocID024755 Rev 9 1/88 This is information on a product in full production. www.st.comContents M24SR16-Y Contents 1 Functional description . 9 1.1 Functional modes . 10 1.1.1 I2C mode 10 1.1.2 Tag mode 10 1.1.3 Dual interface mode 11 2 Signal descriptions . 12 2.1 Serial clock (SCL) . 12 2.2 Serial data (SDA) . 12 2.3 Antenna coil (AC0, AC1) . 12 2.4 Ground (VSS) 12 2.5 Supply voltage (V ) 12 CC 2.5.1 Operating supply voltage V CC . 12 2.5.2 Power-up conditions . 13 2.5.3 Device reset in IC mode 13 2.5.4 Power-down conditions . 13 2.6 RF disable 13 2.7 General purpose output (GPO) 13 2.7.1 Session Open configuration (GPO field = 0xX1 or 0x1X) . 14 2.7.2 WIP Writing in Progress configuration (GPO field = 0xX2 or 0x2X) . 15 2 2.7.3 I C answer ready configuration (GPO field = 0xX3) . 16 2.7.4 MIP NDEF Message writing in Progress configuration (GPO field = 0x3X) . 17 2.7.5 INT Interrupt configuration (GPO field = 0xX4 or 0x4X) 18 2.7.6 State Control configuration (GPO field = 0xX5 or 0x5X) 19 2.7.7 RF busy configuration (GPO field = 0x6X) . 20 3 M24SR16-Y memory management . 21 3.1 Memory structure . 21 3.1.1 File identifier . 21 3.1.2 CC file layout . 21 3.1.3 NDEF file layout . 22 3.1.4 System file layout 23 3.2 Read and write access rights to the memory 25 2/88 DocID024755 Rev 9
