Descriptive summary
UCODE G2iL and G2iL+
With its industry-leading single port read range allowing simple antenna designs, the UCODE G2iL series is ideal for cost-effective RFID applications. UCODE G2iL+ offers industry-first special features such as tag tamper alarm, digital switch, data transfer, read protect, real read range reduction and battery assist mode.
UCODE G2XM and UCODE G2XL
These ICs help keep track of your products throughout manufacturing. Passive RFID chip solutions make pallet-, case- and item-level tracking reliable and cost-effective, helping to stop counterfeiting while speeding up inventory counting. A unique password-protected custom command set includes EAS for increased theft protection, a read protect feature to prevent unauthorized memory access and calibration, allowing optimization of the reader-to-tag communic The ICs are EPCglobal C1G2 1.0.9 certified and compliant to EPCglobal C1G2 1.1.0. They provide unsurpassed UHF performance with reliable operation in dense reader domains and over long read ranges. They feature an extended, 240 bit EPC number and 64 bit tag identifier. Plus, UCODE G2XM provides a 512 bit on-chip dedicated user memory.
UCODE EPC G2
NXP's SL3 ICS1001 is the first chip to comply with EPCglobal's Ultra High Frequency (UHF) Electronic Product Code (EPC) Class 1 Generation 2 (G2) standard. Through a flexible implementation of the application field identifier (AFI), the IC supports both EPCglobal and ISO 18000-6C coding structures. UCODE EPC Gen2 offers 224 bit user memory and a 64 bit tag identifier.
UCODE HSL (High frequency Smart Label)
The SL3 ICS3001 is a dedicated chip for passive, intelligent tags and labels. Its RF interface allows high-speed bi-directional data transmission, while the advanced anti-collision and collision arbitration techniques allow writing to/reading from multiple labels simultaneously. UCODE HSL offers 216 bytes of user memory and a 64 bit unique identifier.
