UCODE® G2iM and G2iM+
NXP’s UCODE G2iM series transponder ICs offers in addition to the leading-edge read range features such as a Tag Tamper Alarm, Data Transfer, Digital Switch, advanced privacy-protection modes and a 640 bit configurable User Memory.
Very high chip sensitivity (-17.5 dBm) enables longer read ranges with simple, single-port antenna designs. In fashion and retail the UCODE G2iM series improve read rates and provide for theft deterrence. In the electronic device market, they are ideally suited for device configuration, activation, production control and PCB tagging. In authentication applications, they 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 UCODE G2iM offers an integrated Product Status Flag (PSF) feature and read protection of the memory content.
The UCODE G2iM+ offers on top of the UCODE G2iM features an integrated tag tamper alarm, digital switch, external supply mode, data transfer mode and real read range reduction. A special feature is the conditional, automatic real read range reduction, where the activation condition can be defined by the user, is newly introduced in the UCODE G2iM+. When connected to a power supply, the READ as well as the WRITE range can be boosted to a sensitivity of -27 dBm.
The UCODE G2iM+ also allows the segmentation of the 640 bit User Memory in up to three segments (open, protected, private) with different access levels (Access- and User Password). For applications which require a longer EPC number the UCODE G2iM+ offers the possibility of up to 448 bit.

Key benefits
End user benefit
- Outstanding User Memory size of 640 bit
- Prevention of unauthorized memory access through different levels of 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 TID range, including a 48 bit serial number
- Reliable operation in dense reader and noisy environments through high interference suppression
Antenna design benefits
- High sensitivity enables small and cost efficient antenna designs
- Low Q-Value eases broad band 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 and Polyimide spacer
- Fast first WRITE or BLOCKWRITE 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 data base.
-
Read Protect
Protects all memory content from unauthorized reading.
-
ChangeConfig
Configures the additional features of the chip like external supply mode, tamper alarm, digital switch, read range reduction, privacy mode activation condition or data transfer.
The UCODE G2iM+ is equipped with a number of additional features. 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.
