BMA456 ASDA, ASCK

[Gideon]

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,

[Minhwan]

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 ??

thanks,

Technically, yes. 

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

Thanks 🙂
