2 GENERAL DESCRIPTION

The I•CODE SLI 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. This IC is the first member of a

product family of smart label ICs based on the ISO standard ISO/IEC 15693.

The I•CODE system offers the possibility of operating labels simultaneously in the field of the reader antenna

(Anticollision). It is designed for long range applications.

2.1 Contactless Energy and Data Transfer

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 I•CODE SLI IC can be

operated without line of sight up to a distance of 1.5 m (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 53 kbit/s.

2.2 Anticollision

An intelligent anticollision function allows to operate more than one tag in the field simultaneously. The

anticollision algorithm selects each tag individually and ensures that the execution of a transaction with a

selected tag is performed correctly without data corruption resulting from other tags in the field.

2.3 Security

Unique Identifiers, which can not be altered, guarantee the uniqueness of each label.
