Can TRF7960A communicate with MLX90129 Sensor Tag?

Other Parts Discussed in Thread: TRF7960A, RF430FRL152H, RF430FRL152HEVM, TIDA-00524, RF430CL331H

Hi, I want to buy a TRF7960A Evaluation Module. But I have a problem. It says it supports for the ISO 15693 standard, the ISO 14443A standard and the ISO 14443B standard. Does it mean it can communicate with any RFID tag supporting the same protocol? Such as, does it support the MLX90129 Sensor Tag / Datalogger IC from the MELEXIS ? I have the MLX90129 datalogger IC, and it supports the ISO 15693 standard. Waiting for your reply. Thanks!

  • Hello Jing,

    As long as the RFID tag follows the ISO15693 protocol then yes the TRF7960AEVM can communicate with it. You should have no issue with that tag and the TRF7960AEVM.

    FYI we also have an ISO15693 RFID Sensor Tag offering, the RF430FRL152H. You can do some datalogging with it as well as it has FRAM memory. Typical applications would have around ~1.5kB of FRAM open for datalogging.

    If you are interested in checking that out as well, you can get the EVM for it: www.ti.com/.../RF430FRL152Hevm
    If you do want to check out the RF430FRL, I recommend to get the TRF7970AEVM instead of the TRF7960AEVM because the demo firmware for the RF430FRL152HEVM is designed for the 7970A module and not the 7960A module.
  • Hi Ralph,
    Thank you for your replying. Actually, if the RFID tag is a passive tag with datalogging, it will be better. Do you have any recommendations for us?
    Thanks!

  • Hello Jing,

    With the RF430FRL152H, the RFID tag can be passively powered with an RF field for operation and then retain datalogged data when no power is present through the use of FRAM memory.

    This would allow you to create a battery-less datalogger.

    Just know that you'd only be able to log data when an RF field is present with such an application.

    Another possibility is to do datalogging with a multi-chip solution where an FRAM MCU controls another of our passive RFID transponders the RF430CL331H: www.ti.com/tool/TIDA-00524

    This method can use either field power or a battery, and if using a battery then you can run in ultra low power modes to conserve battery life and only periodically wake up to take a measurement, store it in FRAM, and then go back to sleep. This application can give you over 40kB of data logging with a battery life of over 5 years.
  • Hi Ralph, thank you so much for your answers. I appreciate it. I will order the RF430FRL152Hevm and the TRF7970AEVM at the distributor's website.

    Thanks again!

    Have a good day!
