Hello fellow developers,
I’m looking for a recommendation for a passive 125 kHz RFID chip with the following requirements:
- Memory size: 2048 bits or higher
- Read/write capability
- Lock bit or another reliable write-protection mechanism
- Suitable for reliable production use
- Currently available / active production line
Any recommendations for suitable NXP chips, alternatives, or compatible reader solutions would be greatly appreciated.
Thanks in advance,
Ben Sella
Hello @benSella,
For new designs, the only LF RFID solution currently recommended in our portfolio is the HITAG µ /Advanced. Please note that this IC offers a maximum total memory capacity of 512 bits.

Hello Habib,
Thank you for your reply and recommendation.
I’m afraid that this chip would not be suitable for our application, as the maximum memory capacity of 512 bits is too limited for our needs.
We are specifically looking for a passive LF RFID solution with at least 2048 bits of memory, along with read/write capability and a reliable locking or write-protection mechanism.
If NXP does not currently offer such a solution, I would still appreciate any recommendation you may have for a suitable alternative.
Thank you again for your help.
Best regards,
Ben Sella
Hello @benSella,
Sorry for taking a while to get back to you.
Unfortunately, HITAG u/Advanced is the only recommended for new designs that supports the low-frequency (LF) RFID.
We have some HF and UHF tags in our portfolio, I can suggest you a recommendation based on these tags in case you are interested. If so, could you provide me more details about your application?
