Product data sheet
1 General description
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.
