Monza R6 / R6-P vs UCODE G2iL / G2iL+

Choose Monza R6 / R6-P if you need optimized high-speed serialization for retail item-level tagging where throughput is critical. The base MR6 provides 96-bit EPC memory with no user memory, suitable for basic inventory tracking at 860–960 MHz. The MR6-P variant adds flexibility with 96/128-bit EPC configurations and 64/32 bits of user memory, plus access/kill password protection and a short-range privacy mode. Both variants comply with EPCglobal Gen2v2 and ISO 18000-63, making them compatible with modern RAIN RFID infrastructure. The R6 family is engineered for environments demanding rapid tag commissioning and standard Gen2 feature sets without requiring tamper detection or advanced privacy modes. Choose UCODE G2iL / G2iL+ if your application requires enhanced security features, tamper detection, or flexible power options. Both variants provide 128-bit EPC memory, 64-bit TID with a 32-bit unique serial number, and 20-year data retention across 840–960 MHz. Security includes 32-bit access and kill passwords, bank-wise read protection for EPC and TID, Product Status Flag for supply chain verification, and Real Read Range Reduction (4R privacy mode) for consumer privacy compliance. The G2iL+ variant uniquely adds Tag Tamper Alarm functionality to detect physical tampering and an optional external VDD pin for applications requiring auxiliary power or digital switching. These chips suit pharmaceutical authentication, high-value asset tracking, or any deployment where tamper evidence and granular access control justify the additional feature set over basic Gen2v2 tags.
