Higgs-9 vs M700 Series

Choose Higgs-9 if you need a single-SKU solution with large EPC memory (496 bits, 62 bytes) and 128 bits (16 bytes) of user memory. The Higgs-9 operates across the full 860–960 MHz UHF range with EPC Gen2v2 authentication, 32-bit access and kill passwords, and untraceable command support. Its 896 bits total memory (112 bytes) makes it suitable for applications requiring extensive serialization or variable data encoding in the EPC bank. The chip's enhanced read sensitivity and comprehensive Gen2v2 feature set support high-throughput retail and logistics environments where a standardized memory configuration simplifies tag deployment and inventory management. The Higgs-9 provides strong security through Gen2v2 authentication and untraceable features without the complexity of managing multiple chip variants. Choose M700 Series if you require application-specific memory configurations across different use cases. The six variants span from M730 (128-bit EPC, no user memory) for cost-sensitive item-level tagging to M780 (496-bit EPC, 128-bit user memory, matching Higgs-9) and M781 (128-bit EPC, 512-bit user memory) for sensor data or extended attribute storage. The M750, M770, M775, and M780 support Gen2v2 Untraceable and Short-range commands, while only M775 offers full Gen2v2 Authenticate capability. Impinj-specific features like Protected Mode and Unkillable Mode (M770/M775/M780) enable tag reuse and prevent accidental decommissioning. All variants share -22 dBm sensitivity and operate on 860–960 MHz RAIN RFID. The M700 family suits organizations managing diverse product lines or pilot programs where memory requirements vary significantly, allowing procurement teams to optimize cost per tag while maintaining reader infrastructure compatibility.
