BL75R05 13.56MHZ Long range RFID Label IC Description The BL75R05 IC is a dedicated chip for intelligent label applications like supply chain management as well as baggage and parcel identification in airline business and mail services. The BL75R05 is designed for long range applications. BL75R05 IC can be operated without line of sight up to a distance of 60cm (gate width). No battery is needed. When the smart label is positioned in the field of an interrogator antenna, the high speed RF communication interface allows to transmit data with up to 53kbit/s. An intelligent anti-collision function allows to operate more than one tag in the field simultaneously. Unique Identifiers, which can not be altered, guarantee the uniqueness of each label. Features • RF Interface (ISO/IEC 15693 compliant) • Contact-less transmission of data and supply energy (no battery needed) • Operating distance: up to 60cm (depending on antenna geometry) • Operating frequency: 13.56 MHz • Fast data transfer: up to 53 kbit/s • High data integrity: 16 Bit CRC, framing • True anti-collision • Electronic Article Surveillance (EAS) • Application Family Identifier (AFI) supported • Data Storage Format Identifier (DSFID) • Additional fast anti-collision read • Write distance equal to read distance • 1024 bits EEPROM, organized in 32 blocks of 4 byte each • Data retention of 10 years • Write endurance 100.000 cycles • Unique identifier for each device • Lock mechanism for each user memory block (write protection) • Lock mechanism for DSFID, AFI, EAS Functional Description Block Diagram Power Clock http://www.belling.com.cn Data series-parallel conversion LB Power Circut Rectifier Clock extractive Power On Reset Voltage Regulator antenna LA RF Analog Inerface Operation M ode IO -1Total 5 Pages Command EEPROM cell Anticollision M em ory Access 12/18/2007 Wrote by ICCD BL75R05 13.56MHZ Long range RFID Label IC The label requires no internal power supply. Its contactless interface generates the power supply and the system clock via the resonant circuitry by inductive coupling to the interrogator. The interface also demodulates data that are transmitted from the interrogator to the Label, and modulates the electromagnetic field for data transmission from the Label to the interrogator. Data are stored in a non-volatile memory (EEPROM). The EEPROM has a memory capacity of 1024 bit and is organised in 32 blocks consisting of 4 bytes each (1 block = 32 bits). Memory Organization EEPROM memory organization The values (in hexadecimal notation) shown in the table above are stored in the EEPROM after the wafer production process. The contents of blocks marked with ‘x’ in the table are not defined at delivery. With read and write commands only blocks 0 to 27 can be addressed. 1 UNIQUE IDENTIFIER The 64 bit unique identifier (UID) is programmed during the production process according to ISO/IEC 15693-3 and cannot be changed afterwards.The numbering of the 64 bits is done according to ISO/IEC 15693-3 starting with the LSB 1 and ending with the MSB 64. This is in contrast to the general used bit numbering within a byte.

This 8-bit value is located at Byte 2 in Block -2 as shown in the following figure and is only evaluated if the AFI flag is set in the reader command. For details please refer to ISO 15693-3. Block -2，Byte 2 MSB X LSB X X X X X X e AFI 4 DSF ID The Data Storage Format Identifier (DSFID) is located at Byte 3 in Block –2. For details please refer to ISO/IEC 15693-3. Block -2，Byte 3 MSB X LSB X X X X X X e DSFID 5 WRITE ACCESS CONDITIONS The Write Access Condition bits in block -1 determine the write access conditions for each of the 28 user blocks and the special data block. These bits can be set only to 1 with a lock command (and never be changed back to 0), i.e. already write protected blocks can never be written to from this moment on. Communication Principle For detailed description of the protocol and timing please refer to ISO/IEC 15693-2 (modulation, bit-coding, framing) and 15693-3 (anti-collision, timing, protocol).
