CC1101: cc1101 - Still a good choice for a TPMS receiver in 2025?

Part Number: CC1101
Other Parts Discussed in Thread: CC113L, CC110L, CC115L, CC1125, CC1120, CC1201, CC1200

Tool/software:

Hello, Im looking for an up to date 433MHz receiver for a TPMS (tyre pressure monitoring) application.  Ive used CC1101 before, but it seems that part is quite old.  I see referenced to it dating back to 2007 at least.  So I am wondering if there is a more up-to-date option?  Sensitivity can be an issue, especially on large trailers, where we had some difficulty before, and hence any advances in sensitivity would be helpful.  Any better options these days? TIA

    Hi,

    It depends on your requirements. Are you looking to design a system that can communicate with older packet formats or are you designing your system from scratch?

    The current transceivers available (at the time of writing) that could be considered are:

    • CC1101 and its low-cost versions (CC110L, CC113L/CC115L).
    • CC1120/CC1125 (the CC1125 is for narrowband applications)
    • CC1200/CC1201

    The modulation scheme being considered is important, as "Asynchronous Mode"/"Transparent Serial Mode" (it is called one of the two depending on the device) may be required in order to receive packets that cannot be handled by the built-in packet handling functionality.

    Regards,

    Zack

    Well, we are designing the receiving part of the TPMS 'system' only, and we would like to aim for compatibility with a wide range of sensors.  I doubt that these TPMS sensors last 20 years, so I assume they will be reasonably up to date designs.  I wil ltake a look at some of those other options you listed.  Thanks for the suggestions.
