Active RFID and CC1310

Jesper Hansen

Other Parts Discussed in Thread: TRF7970A

From the http://www.ti.com/lit/ds/symlink/cc1310.pdf 

To be honest I am a little confused about active RFID, passive RFID, NFC in active mode, NFC in passive mode and the cabalilities of these.

 

Can someone provide me with further information about this active RFID tag.

1. What is the typical application use cases? Pairing of a device?

2. Can this RFID tag both send and recive data. For instance, can I send a simpel 16 bit UUID from a device with a TRF7970A to this active RFID? And what about the opposite direction?

3. What is the main difference between an active RFID and for example RF430CL330H 

 

All comments are very welcome :) 

 

Best Regards,

 

Jesper

    Jesper,

    There are a lot of question in one post.

    1. NFC is a subset of RFID, NFC uses 134KHz where RFID can be 134kHz, 13MHz or even 800-900MHz.
    2. The typical use cases are
      1. Secure paring of WIFI or BT
      2. Tracking of inventory
      3. NFC to securely update firmware images over the air (short range, hinse secure)
    3. Yes, tags can both send and receive data.
    4. Active versus passive, just indicates if the "TAG" side, low cost high volume side has its own battery source or it requires power from incoming interrogator RF signal.
    5. The CC13xx can be used to implement active tags at 800-900MHz only.
