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.

2 EAS FUNCTION
The LSB of Byte 1 in Block –2 holds the EAS bit (Electronic Article Surveillance mode active
the label responds to an EAS command)
