NXP G2XM

The EPC Global UHF Second Generation standard allows for large-scale commercialization of UHF EPC technology for passive smart labels. The main application areas will focus in particular on global supply chain management and logistics, with special consideration for European and US regulations to ensure that effective working distances of several meters are achieved.

The SL3ICS1002 G2XM is a dedicated passive smart tag chip that supports the EPCglobal Class 1 Generation 2 UHF RFID standard. It is especially suited for applications that require a working distance of several meters and high collision resistance.

The SL3ICS1002 G2XM is part of the NXP Semiconductors UCode product family. The entire UCode product family features collision avoidance and collision arbitration. This enables the reader to read multiple tags simultaneously within its antenna coverage area. Tags based on the UCode EPC G2 standard do not require an external power supply.

Its contactless interface is powered by the propagation energy transfer from the interrogator (read/write device) through an antenna circuit, and the system clock is generated by an on-chip oscillator. The data transmitted from the interrogator to the tag is demodulated by the interface, which also modulates the electromagnetic field of the interrogator to enable the tag to transmit data to the interrogator. The tag can operate without line-of-sight contact or battery power as long as it is connected to a dedicated antenna in the target frequency range. The high-speed wireless interface supports bi-directional data transmission when the tag is within the interrogator's operating range.
