Higgs-3 vs UCODE G2iL / G2iL+

Choose Higgs-3 if you require substantial user memory (512 bits or 64 bytes) for storing application data beyond the EPC identifier, or if you need flexible EPC memory allocation ranging from 96 to 480 bits. The Higgs-3 provides 800 bits total memory including the 512-bit user bank, 64-bit TID with unique serial number, and standard 32-bit access and kill passwords. Its Dynamic Authentication fingerprint feature enables secure traceability. Security features include block-wise permalock and read password protection in 64-bit blocks for the user memory bank. The chip operates across the full UHF RFID band from 860-960 MHz and complies with EPC Global Class 1 Gen 2 V1.2.0 and ISO/IEC 18000-6C standards, making it suitable for supply chain applications requiring extended data storage or variable EPC lengths. Choose UCODE G2iL or G2iL+ if you need advanced security features like Tag Tamper Alarm (G2iL+ variant), Real Read Range Reduction for privacy applications, or bank-wise read protection for EPC and TID memory. The UCODE G2iL series features fixed 128-bit EPC memory with no user memory bank, plus 64-bit TID containing a 32-bit unique serial number. The G2iL+ variant adds optional external supply mode via a VDD pin and Tag Tamper Alarm functionality for anti-counterfeiting and authentication. The 4R privacy mode reduces read range on demand for consumer privacy protection, while the Product Status Flag tracks item lifecycle. Operating from 840-960 MHz with 20-year data retention, these chips suit retail, authentication, and brand protection applications where tamper detection and privacy features outweigh the need for additional user memory storage.
