Monza R6 / R6-P vs UCODE DNA

Choose Monza R6 / R6-P if you need a cost-optimized UHF RAIN RFID solution for high-volume retail item tagging and supply chain applications where basic identification is sufficient. The Monza R6 provides 96 bits of EPC memory with no user memory, suitable for simple serialization. The Monza R6-P variant extends this to 96 or 128 bits EPC with 64 or 32 bits of user memory respectively, and adds Access and Kill password protection (32 bits each) plus a short-range mode for privacy. Both operate across 860-960 MHz and comply with EPCglobal Gen2v2 and ISO 18000-63. These chips excel in applications requiring fast read rates and minimal data storage, such as apparel tagging, inventory tracking, and point-of-sale operations where the primary requirement is unique identification rather than extensive data storage or cryptographic authentication. Choose UCODE DNA if you require advanced security features and significantly larger memory for brand protection, anti-counterfeiting, or applications demanding cryptographic authentication. The UCODE DNA offers 256 bit EPC in G2iM mode or 128-448 bit EPC in G2iM+ mode, combined with 640 bits of user memory (segmentable in G2iM+). It operates across 840-960 MHz per EPC Gen2v1.2.0 and ISO 18000-63. Security capabilities include AES-128 cryptographic authentication, three separate 32-bit passwords (Kill, Access, and User in G2iM+), bank-wise read protection for EPC, TID, and User Memory, BlockPermalock, and tag tamper alarm (G2iM+). The 96-bit TID includes a 48-bit unique serial number plus 112 bits of User TID. The G2iM+ variant adds conditional read range reduction and a digital switch/data transfer mode via VDD and OUT pads for sensor integration or external communication. This chip is ideal for pharmaceuticals, luxury goods authentication, secure document tracking, and any application where data integrity and cryptographic verification are mandatory requirements.
