The ISO 18000-3 mode 3/EPC Class-1 HF standard allows the commercialized provision
of mass adoption of HF RFID technology for passive smart tags and labels. Main fields of
applications are supply chain management and logistics for worldwide use.
The ICODE ILT is a dedicated chip for passive, intelligent tags and labels supporting the
ISO 18000-3 mode 3 RFID standard. It is especially suited for applications where reliable
identification and high anti-collision rates are required.
The ICODE ILT is a product out of the NXP Semiconductors ICODE product family. The
entire ICODE product family offers anti-collision functionality. This allows a reader to
simultaneously operate multiple labels/tags within its antenna field. A ICODE ILT based
label/tag requires no external power supply.
Its contactless interface generates the power supply via the antenna circuit by inductive
energy transmission from the interrogator (reader), while the system clock is extracted
from the magnetic field. Data transmitted from interrogator to label/tag is demodulated by
the interface, and it also modulates the interrogator's magnetic field for data transmission
from label/tag to interrogator. A label/tag can be operated without the need for line of sight
or battery, as long as it is connected to a dedicated antenna for the targeted frequency
range. When the label/tag is within the interrogator's operating range, the high-speed
wireless interface allows data transmission in both directions.
