    BME280 SPI maximum capacitive and inductive load

    BME280 SPI maximum capacitive and inductive load

    Hello,

    Does anyone know if there is a maximum capacitive/inductive load for the BME280 SPI protocol?

    In the datasheet SPI timings table (capture in attachments), they mention 25pF as a usage condition for SDO but I am not sure if it is the maximum capacitive load for the BME280

    Thanks

    Hello Jet,

    Do you know if the input/output impedance values of the BME280 can be found in any documentation?

    It is for the impedance matching problematic

    Thanks,

    Hi Sir:

        Sorry, I don't have any document. Actually the normal connection with BME280 have no the impedance matching problematic.

        The impedance matching problematic is only based on experience to verify, not only for BME280 but also many other IC design have the same problem.
