TI UHF Gen2 Protocol - vijaynewy - 10-04-2017 TI UHF Gen2 Protocol [attachment=17447] General 1.2 System Description General Large retailers, such as Wal-Mart and Target in the USA and Metro in the European Union (EU), have issued mandates to their suppliers to ship cases and pallets of goods/products with radio-frequency identification (RFid) smart labels attached. TI s Generation 2 (Gen2) IC is intended to be used primarily in case- and pallet-level retail supply-chain applications, and is based on the EPCglobal Gen2 Specification Version 1.0.9 approved in December 2004. TI s UHF Gen2 IC operates with extremely low power and yet provides long read and write ranges, fast data transfer, and high smart-label throughput, which are all crucial for the following applications: Express parcel delivery Airline baggage handling Distribution logistics and supply-chain management Building access badges Asset tagging This low-power passive IC is designed to operate on the energy extracted from the radio frequency (RF) signals transmitted from the reader (interrogator) via its antenna. The IC does not require a battery to operate. The IC returns data to the reader using modulated backscatter. To form a functional transponder, the IC (sometimes called a die) requires bonding to an antenna. When the parameters of this antenna match the characteristics of the IC, the antenna resonates at the required frequency and is capable of receiving power and instructions and returning data. Product Description 1.4 Functional Description Product Description The IC has been manufactured to fully meet the EPCglobal Gen2 specification and can be used to create a functional transponder in three main ways: Forming an inlay The TI Gen2 IC can be bonded to an antenna, printed on a plastic or paper substrate, or etched from copper or aluminum. This creates an inlay that can then be converted into a wet inlay having a peel-off adhesive layer, or integrated directly into a smart label. Currently, the majority of the RFID applications use inlays to make smart labels for use on cases and pallets. Direct attach to label The TI Gen2 IC can be mounted directly on an antenna that is part of a printed label substrate, to construct a smart label. Currently, a number of manufacturers are exploring this approach. Attach to FR4 The TI Gen2 IC can also be mounted on FR4 antennas or antennas designed on printed circuit boards. The IC is composed of a number of building blocks that include the analog front end (AFE), which converts RF to digital, digital logic, and memory. The digital logic includes a state machine, where groups of commands become available once the chip has transitioned to the correct state. This manual describes the functional operation of the state machine. |
