Hello,

I am running a bcm20737s at 2.8v. i am also powering a sensor at 2.8v which will communicate with the bcm20737s over i2c.

what is the logic detection of the bcm20737s? Also it is recomened that i put a 10k pull up on my i2c lines. As i am running at 2.8v should this be adjusted?

Luke.

Yes, 10K is recommended.

Yes 10K is recommended but is that at 3.3v. I will be running mine at 2.8v?

The logic level changes as the voltage changes?
