NXP Ucode EPC G2

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

The UCODE EPC G2 IC is a dedicated passive smart label chip that supports the EPCglobal Class 1 Generation 2 UHF RFID standard. It is particularly suitable for applications that require a working distance of several meters and high collision resistance.

The UCODE EPC G2 IC is part of the NXP Semiconductors UCODE product family. The entire UCODE product family is equipped with collision avoidance and collision arbitration. This enables the reader to read multiple tags simultaneously within its antenna coverage area. UCODE EPC G2-based tags require no 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 sent 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 operates 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.
