    BMA456 ASDA, ASCK

    Dear,

    I would like to know how to design ASDA and ASCK if I don't use them.

    In the shuttle schematic, it is connected to vddio through 2.2k ohm resistor.

    I am wondering it can be affected to power consumption. And is it possible to make those pins as No Connection?

     

    Thanks,

    You can leave it without connection, can check this information page 88.

    Hi minwhan,

    thanks for your reply.

    it shows VDDIO/GND/NC in BMA456 datasheet.
    It means I can connect vddio and GND as well ??

    Technically, yes. 

    But, I'd like to recommend as DNC due to space point of view. 

    Thanks 🙂
