1. General 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.

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

5. Block diagram
The SL3 ICS 10 IC consists of three major blocks:
Analog RF Interface
Digital Controller
EEPROM
The analog part provides stable supply voltage and demodulates data received from the
reader for being processed by the digital part. Further, the modulation transistor of the
analog part transmits data back to the reader.
The digital section includes the state machines, processes the protocol and handles
communication with the EEPROM, which contains the EPC and the user data.
