2 DESCRIPTION
The I•CODE UID Smart Label IC is a dedicated chip for radio frequency identification on item level. This IC is a member
of the well known and established in the contactless identification market I•CODE product family of smart label ICs.
The I•CODE system offers the possibility of operating smart labels simultaneously in the field of the reader antenna
(Anticollision). It is designed for long range applications.
Due to the open marketing strategy of Philips Semiconductors there are various manufacturers available for both the
smart labels as well as for the Read/Write devices (RWD).
2.1 Contactless Energy and Data Transfer
Whenever connected to a very simple and cost effective type of antenna (as a result of the carrier frequency
fc = 13.56 MHz) made out of a few windings printed, winded, etched or punched coil the I•CODE UID Smart Label IC can
be operated without any line of sight up to a distance of 1.5 m (gate width). No battery is needed. When the I•CODE UID
smart label is positioned in the field of an RWD 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 many I•CODE UID smart labels in the field simultaneously. The
anticollision algorithm enables that each smart label in the bulk of many labels can be identified individually.
2.3 Customer Application Support and Training
Within the dedicated CAS team at the BL Identification.

5.3.1 CODING
A logic 0 starts with 4 pulses of fc/32 (~423.75 kHz) sub-carrier, followed by an un-modulated time of 128/fc (~9.44 µs),
as shown in following Figure 6.
18.88 µs
Low damping
High damping
Fig.6 Modulation for logic 0.
The waveforms in Figure 6, and similar diagrams to follow, represent logic states illustrating the periods of high damping
and low damping of the antenna tuned circuit. They are not amplitudes of signals, but high oscillation amplitude will in
fact occur during the high parts of the waveforms.
A logic 1 starts with an un-modulated time of 128/fc (~9.44 µs) followed by 4 pulses of fc/32 (~423.75 kHz) sub-carrier,
as shown in following Figure 7.
18.88 µs
Low damping
High damping

5.3.2 BAUD RATE
The baud rate in theI•CODE UID smart label to RWD link is 52.969 kbit/s (fc/256).
