Introduction

ICODE SLIX-S is an IC designed for smart label applications, addressing the growing demand for enhanced security, increased memory capacity, and customer privacy protection. It is the third generation of a smart label IC family based on ISO/IEC 15693 and ISO/IEC 18000-3 standards, continuing NXP's success in vicinity identification systems. The ICODE system supports simultaneous operation of multiple tags within the reader antenna field (anti-collision) and is designed for long-range applications. The IC obtains energy and transfers data contactlessly without a battery, and when connected to a simple coil antenna — printed, wound, etched, or stamped — operates at distances of up to 1.5 m (door width) without line-of-sight, thanks to the 13.56 MHz carrier frequency. When a smart label is placed within the reader antenna field, its high-speed RF communication interface supports data transfer rates of up to 53 kbit/s. The intelligent anti-collision feature allows multiple tags to operate simultaneously within the field; the algorithm individually selects each tag and ensures correct transaction execution with the selected tag, free from data corruption caused by other tags in the field.

In terms of security and privacy, the IC features an immutable identifier ensuring the uniqueness of each tag; supports memory management with password protection for read/write access control on pages (1 page = 4 blocks, 4 bytes per block) to prevent counterfeiting; provides a 32-bit kill password enabling permanent tag destruction via the DESTROY SLIX-S command; provides a 32-bit privacy password enabling privacy mode via the ENABLE PRIVACY command, in which the tag responds only to the GET RANDOM NUMBER command until the correct privacy password is received — a mode specifically designed to meet growing customer privacy protection requirements; and provides a 32-bit EAS/AFI password protecting the electronic article surveillance status, EAS ID, and/or the ability to modify the application family identifier value.
