SL3S1203_1213
UCODE G2iL and G2iL+
Data retention: 20 years
Broad international operating frequency: from 840 MHz to 960 MHz
Long read/write ranges due to extremely low power design
Reliable operation of multiple tags due to advanced anti-collision
READ protection
WRITE Lock
Wide specified temperature range: 40 C up to +85 C
2.2 Key benefits
2.2.1 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
2.2.2 Antenna design benefits
High sensitivity enables small and cost efficient antenna designs
Low Q-Value eases broad band antenna design for global usage
2.2.3 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
2.3 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 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.
