Higgs-4 vs M775

Choose Higgs-4 if you need significantly more programmable memory capacity for your application. The Higgs-4 provides 544 bits total memory with 128 bits of user memory (16 bytes) compared to the M775's 32 bits (4 bytes), offering four times the user-writable storage. This makes it better suited for applications requiring additional data storage beyond the standard EPC identifier, such as batch numbers, expiration dates, or manufacturing parameters. The Higgs-4 also includes advanced security with Dynamic Authentication anti-cloning fingerprint technology, BlockPermaLock for 32-bit memory blocks, and BlockReadLock functionality. Both chips support the same EPC Class-1 Generation-2 V1.2.0 and ISO/IEC 18000-6C protocols, operate across the full 860–960 MHz UHF frequency range, and feature 32-bit access and kill passwords plus 64-bit factory-programmed UIDs. The Higgs-4 provides 320 bits of customer-programmable memory total. Choose M775 if you prioritize cost optimization and your application requires minimal user memory beyond EPC identification. The M775 delivers the same 128-bit EPC memory as the Higgs-4 and supports the same EPC Gen 2 and RAIN RFID standards, making it fully interoperable for standard retail and inventory tracking workflows. Both chips feature FastID technology for rapid inventory scanning, enabling high-speed read operations in dense tag environments. The M775 is marketed with enhanced read range capabilities, potentially offering better performance in challenging RF environments or at greater distances. With 64-bit TID memory for chip serialization and the standard 32-bit access and kill password security, the M775 meets basic security requirements for item-level tagging. For applications focused purely on identification and tracking without extensive on-chip data storage needs, the M775's reduced memory footprint may translate to lower chip costs while maintaining full Gen2 protocol compliance.
