FAQ's
What is UCODE Nxm?
UCODE Nxm is NXP's high-memory RAIN RFID IC, combining high performance with up to 880 bits of configurable memory.
What is configurable memory?
UCODE Nxm lets users allocate memory between EPC and User Memory, enabling one IC to support multiple applications.
What makes UCODE Nxm different from other RAIN RFID ICs?
UCODE Nxm combines high sensitivity, configurable memory and advanced features such as Self-Adjust, Memory Safeguard, Brand Identifier and Untraceable privacy.
Why store data on the tag instead of only in the cloud?
It keeps critical information with the item, even when backend connectivity is unavailable.
What is Memory Safeguard?
Memory Safeguard helps protect stored data using error detection and correction mechanisms.
When should I choose UCODE Nxm?
Choose UCODE Nxm when applications require additional data, such as process status, lifecycle records, URLs or digital product information, to be stored on the tag.
What is the main difference between UCODE Nxm and UCODE 9xm?
UCODE Nxm builds on UCODE 9xm with larger configurable memory and enhanced privacy features for data-rich applications.
Is UCODE Nxm compatible with existing UCODE 9xm designs?
Yes. UCODE Nxm provides an easy migration path with compatible design attributes for drop-in antenna replacement.
How does UCODE Nxm compare to UCODE X?
UCODE X is optimized for identification performance, while UCODE Nxm adds configurable memory for data-rich applications.
Which applications are UCODE Nxm designed for?
UCODE Nxm is designed for manufacturing, automotive, healthcare, aviation, supply chain, baggage tracking and consumer engagement applications. It also supports DPP use cases by storing key product information directly on the tag throughout the product lifecycle. Its configurable memory also supports GS1 TDS 2.3 encoding.
