描述 Description

The EPC global UHF Generation 2 Standard allows the commercialised provision of mass adaption of UHF EPC technology for passive smart tags and labels. Main fields of applications will be especially the supply chain management and logistics for worldwide use with especial consideration of European and US regulations to ensure that operating distances of several meters can be realized.

The UCODE® EPC G2 IC is a dedicated chip for passive, intelligent tags and labels supporting the EPCglobal Class 1 Generation 2 UHF RFID standard. It is especially suited for applications where operating distances of several meters and high anti-collision rates are required.

The UCODE EPC G2 IC is a product out of the NXP® Semiconductors UCODE product family. The entire UCODE product family offers anti-collision and collision arbitration functionality. This allows a reader to simultaneously operate multiple labels / tags within its antenna field. A UCODE EPC G2 based label / tag requires no external power supply.

Its contactless interface generates the power supply via the antenna circuit by propagative energy transmission from the interrogator (read / write device), while the system clock is generated by an on-chip oscillator. Data transmitted from interrogator to label / tag is demodulated by the interface, and it also modulates the interrogator’s electromagnetic field for data transmission from label / tag to interrogator. A label / tag can be operated without the need for line of sight or battery, as long as it is connected to a dedicated antenna for the targeted frequency range. When the label / tag is within the interrogator’s operating range, the high-speed wireless interface allows data transmission in both directions.

RF Interface



Contact-less transmission of data and supply energy (no battery needed)

Long-range operating distance

Operating frequency within the released operating bands from 860 MHz to 960 MHz

High data integrity: 16 bit CRC, framing

High anti-collision and inventory speed

Data rates:
R -> T: 40 – 160 kbps,

T -> R: 40 – 465 kbps (Divide ratio DR = 8) or 95 – 640 kbps (DR = 64/3)




Uses a slotted random anti-collision algorithm where the UCODE EPC G2 IC loads a random (or pseudo-random) number into a slot counter, decrement this slot counter based on interrogator commands, and reply to the interrogator when their slot counter reaches zero. Supports the full mandatory command set as well as optional and Customer commands according to the standard



Memory



96 bit EPC numbers supported

64 bit tag identifier (TID)

32 bit kill password to permanently disable the tag

32 bit access password to allow a transition into the secured transmission state

224 bit user memory with free definable memory organization

Inventoried flags and selected flag support the handling of persistence information



Security



Lock mechanism (write protection) for individual passwords and individual memory banks allow for permanent lock (permalock) status of a password or memory bank.
