UCODE G2iL and G2iL+ | NXP Semiconductors

Overview

NXP’s UCODE G2iL series transponder ICs offer leading-edge read range and support industry-first features such as a Tag Tamper Alarm, Data Transfer, Digital Switch, and advanced privacy-protection modes.

Very high chip sensitivity (-18 dBm) enables longer read ranges with simple, single-port antenna designs. When connected to a power supply, the READ as well as the WRITE range can be boosted to a sensitivity of -27 dBm. In fashion and retail the UCODE G2iL series improve read rates and provide for theft deterrence. For consumer electronics the UCODE G2iL series is suited for device configuration, activation, production control, and PCB tagging. In authentication applications the transponders can be used to protect brands and guard against counterfeiting. They can also be used to tag containers, electronic vehicles, airline baggage, and more.

In addition to the EPC specifications the G2iL offers an integrated Product Status Flag (PSF) feature and read protection of the memory content.

On top of the G2iL features the G2iL+ offers an integrated tag tamper alarm, RF field detection, digital switch, external supply mode, read range reduction and data transfer mode.

WRITE Lock
Wide specified temperature range: -40 °C up to +85 °C

End-user benefit

Prevention of unauthorized memory access through read protection
Indication of tag tampering attempt by use of the tag tamper alarm feature
Electronic device configuration and / or activation by the use of the digital switch / data transfer mode
Theft deterrence supported by the PSF feature (PSF alarm or EPC code)
Small label sizes, long read ranges due to high chip sensitivity
Product identification through unalterable extended TID range, including a 32-bit serial number
Reliable operation in dense reader and noisy environments through high interference suppression

Antenna design benefits

High sensitivity enables small and costs efficient antenna designs
Low Q-Value eases broadband antenna design for global usage

Label manufacturer benefit

Consistent performance on different materials due to low Q-factor
Ease of assembly and high assembly yields through large chip input capacitance
Fast first WRITE of the EPC memory for fast label initialization

Custom commands

PSF Alarm
Built-in PSF (Product Status Flag), enables the UHF RFID tag to be used as EAS tag (Electronic Article Surveillance) tag without the need for a back-end database
Read Protect
Protects all memory content including CRC16 from unauthorized reading
ChangeConfig
Configures the additional features of the chip like external supply mode, tamper alarm, digital switch, read range reduction or data transfer

The UCODE G2iL is equipped with a number of additional features and custom commands. Nevertheless, the chip is designed in a way standard EPCglobal READ/WRITE/ACCESS commands can be used to operate the features. No custom commands are needed to take advantage of all the features in case of unlocked EPC memory.
