Chip capabilities and selection notes
Self-Adjust auto-tuning, Memory Safeguard data integrity, dynamic backscatter and a pre-serialized 96-bit EPC; works with single-slit antennas.
The chip is one part of the RFID design. Antenna geometry, label layers, tagged material and reader setup all influence the result. Confirm the footprint, data format and mounting condition when requesting samples.

UHF How ordering works
- 01
Specify
Share surface, read distance, chip preference and volume. We shortlist tags that fit.
- 02
Sample
Receive sample tags of the shortlisted designs to try in your own setup.
- 03
Validate
Test on your items, readers and printers. We adjust chip, size or format if needed.
- 04
Produce & ship
Volume production with 100% inline electrical test, then export shipping.
Frequently asked questions
How do I choose a tag with NXP UCODE 9?
Match the reader protocol and required memory first, then compare antenna size and mounting material. Test the finished tag on the intended object before a volume order.
Can the datasheet tell me how far the label reads?
Chip specifications describe the integrated circuit. Finished-tag read range depends on the antenna, reader, power and tagged material; use measured sample results for qualification.
Can I request another format or chip option?
Share the desired footprint, format and encoding requirements. We will confirm a suitable chip and antenna combination and arrange the sample configuration before quoting bulk.
