Conflict between UCODE 7 model number in datasheet and gs1 website

[Milad_b80]

Hi, according to GS1 MDID assignment which its link is below, the model number of UCODE 7 is assigned to 810 but in the UCODE 7 datasheet it says it's model number is 890.

The MDID assignment page:

https://www.gs1.org/docs/epc/mdid_list.json

The datasheet link:

https://www.nxp.com/docs/en/data-sheet/SL3S1204.pdf

Page 20.

Thanks.

Hello sir,

I'm not sure about the GS1 json you are sharing. According to the GS1 site NXP's 9bit MDID is:

0 0000 0110. Please check it here: Mask Designer ID (MDID) Assignment | GS1

According to our Datasheet, the MDID is: 100[0 0000 0110]b (806) 

These 9bits are fixed.

I hope this information may have been useful.

Thanks for your reply, but I'm not talking about NXP's MDID (which is 806), I'm talking about the model number of the UCODE 7 product and the difference between datasheet number and the json file which is provided by GS1.

Sorry, I understand.

My recommendation would be to please check this with GS1. According to the GS1's EPC® Radio-Frequency Identity Generation-2 UHF RFID Standard. In section 6.3.2.1.3 TID Memory is mentioned that The Tag Model Number is Tag-manufacturer-defined.

The UCODE 7 Tag Model number is 890h as shown in our Datasheet.

I've emailed GS1 and requested a response from them. As soon as I receive a reply, I'll share it here. My goal is to identify the model of tags I have and need a reference that can help me extract this information. 

Thanks.
