CC3220SF: SOP1 resistance value?

Part Number: CC3220SF

The CC3220-LAUNCHXL circuit SOP 1 are 270 ohm and 100 k.

If the SOP(2:0) uses 010, can I use 270 ohm without 100K?

The 3220SF DATASHEET says pull-up. Can I use a different value?

-Thank you.-

Hi kwon,

For SOP1, the pull up and pull down values should be 270 and 100k, respectively. Please refer to our reference design here.

If sop1 is used high, why should I use 270 and 100k together? Can't I just use pull-up?

I wonder why you should use both together(270 pull-up & 100k pull-down).

Hi kwon,

Yes, but when the board is in production, there is no need to pull SOP1 high. The SOP config can be left as 000 at this point. Although small, you can lower current consumption this way.
