5 Functional Description
5.1 Basic Features
The ICODE1 Label IC is a dedicated chip for intelligent label applications like logistics and retail
(including EAS) as well as baggage and parcel identification in airline business and mail services.
The ICODE system offers the possibility of operating labels simultaneously in the field of the
reader antenna (Anticollision). It is designed for long range applications.
Whenever connected to a very simple and cheap type of antenna (as a result of the 13.56 MHz
carrier frequency) made out of a few windings printed, winded, etched or punched coil the
ICODE1 Label IC can be operated without line of sight up to a distance of 1.5 m (gate width).
5.2 Block Diagram of the 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 reader. The interface
also demodulates data that are transmitted from the reader to the ICODE Label, and modulates the
electromagnetic field for data transmission from the ICODE Label to the reader.
Data are stored in a non-volatile memory (EEPROM). The EEPROM has a memory capacity of 512
bit and is organised in 16 blocks consisting of 4 bytes each (1 block = 32 bits). The higher 12 blocks
contain user data and the lowest 4 blocks contain the serial number, the write access conditions and
some configuration bits.
