描述 Description

The UHF EPCglobal Generation 2 standard allows the commercialized provision of massadoption of UHF RFID technology for passive smart tags and labels. Main fields ofapplications are supply chain management and logistics for worldwide use with specialconsideration of European, US and Chinese frequencies to ensure that operatingdistances of several meters can be realized.
The G2X is a dedicated chip for passive, intelligent tags and labels supporting theEPCglobal Class 1 Generation 2 UHF RFID standard. It is especially suited forapplications where operating distances of several meters and high anti-collision rates arerequired.
The G2X is a product out of the NXP Semiconductors UCODE product family. The entireUCODE product family offers anti-collision and collision arbitration functionality. Thisallows a reader to simultaneously operate multiple labels/tags within its antenna field.A UCODE G2X based label/ tag requires no external power supply.
Its contact-less interface generates the power supply via the antenna circuit bypropagative energy transmission from the interrogator (reader), while the system clock isgenerated by an on-chip oscillator. Data transmitted from interrogator to label/tag isdemodulated by the interface, and it also modulates the interrogator’s electromagneticfield for data transmission from label/tag to interrogator. A label/tag can be operatedwithout the need for line of sight or battery, as long as it is connected to a dedicatedantenna for the targeted frequency range. When the label/tag is within the interrogator’soperating range, the high-speed wireless interface allows data transmission in bothdirections.
In addition to the EPC specifications the G2X offers an integrated EAS (Electronic ArticleSurveillance) feature and read protection of the memory content. On top of thespecification of the G2XL the G2XM offers 512-bit of user memory.
