Engineering Brief
The UCODE G2iL/G2iL+ is an EPC Gen2 v1.2.0 compliant UHF RFID transponder IC offering industry-leading sensitivity of -18 dBm for extended read range with simple antenna designs. The G2iL features integrated Product Status Flag (PSF) for EAS applications, bank-wise read protection, and Real Read Range Reduction (4R) privacy mode. The G2iL+ variant adds advanced features including Tag Tamper Alarm for security seals, digital switch/I/O for device activation, data transfer mode for external communication, and external supply mode boosting sensitivity to -27 dBm for equal read/write ranges. Available in 75 µm and 120 µm wafer, XSON6 package, and FCS2 strap formats.

Frequently Asked Questions
What is the read sensitivity of the UCODE G2iL chip?
The UCODE G2iL has a read sensitivity of -18 dBm. The G2iL+ variant can reach -27 dBm sensitivity when operated in external supply mode via the VDD pin, enabling equal read and write ranges.
What is the difference between UCODE G2iL and G2iL+?
The G2iL+ adds Tag Tamper Alarm for security seals, digital switch/I/O capability for device activation, data transfer mode for external sensor communication, and external supply mode. Both share the same core memory (128-bit EPC) and -18 dBm base sensitivity.
Does UCODE G2iL support EPC Gen2 v2 features?
No, the UCODE G2iL/G2iL+ is compliant with EPC Class-1 Generation-2 UHF RFID v1.2.0 specification, not Gen2v2.
What privacy features does the UCODE G2iL have?
The UCODE G2iL supports Real Read Range Reduction (4R privacy mode) to limit read distance, bank-wise read protection for EPC and TID memory, plus 32-bit access and kill passwords for controlled access and permanent deactivation.
What is the Tag Tamper Alarm feature on UCODE G2iL+?
Tag Tamper Alarm is a security feature exclusive to the G2iL+ that detects physical tampering of security seals or tagged items, enabling applications in anti-counterfeiting and seal integrity verification.
What memory does the UCODE G2iL have?
The UCODE G2iL contains 128-bit EPC memory, 64-bit TID with a 32-bit unique serial number, 32-bit access password, and 32-bit kill password. Data retention is rated at 20 years.
