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.
