The UCODE DNA from NXP is a UHF RFID Tag IC designed to target secure asset tagging applications with good long-range performance. It has a read range of up to 15 meters, a read sensitivity of -19 dBm, AES authentication sensitivity of -18 dBm, and a write sensitivity of -11 dBm. The tag has an encoding speed of 32 bits per 1.5 ms and can work in parallel encoding mode by encoding more than 100 items in 60 ms. This RFID tag supports up to two 128-bit AES authentication keys, has an EPC memory of 448 bits and supports self pre-serialization for 96 bits EPC. It has a TID memory of 96 bits and a user memory of 3072 bits. The RFID tag is compatible with a single-slit antenna and has write cycle endurance of over 100,000.

The UCODE DNA RFID IC is designed in compliance with GS1™ UHF RFID Gen2 v2.0, ISO/IEC 29167-10 standards. This RFID tag is available as a bumped die and is suitable for Automatic vehicle ID (e.g. electronic toll collection, electronic vehicle registration), Visitor/staff access control and location service (e.g. at theme parks, at large events), Visitor classification and pre-processing (e.g. at border crossings or stadium entry points), Retail supply chain management/brand protection (e.g. expensive wines or branded luxury fashion items), and Asset tracking (e.g. for high-value assets).
