CC3220SF: SOP2(Pin 21) pull-down resistor 100K Ohm can be used ? reference circuit value is 2.7K Ohm.

Hi, Support Team,

Our product use CC3220SF SoC.

My question:

Can R51 resistor replaced with 100K Ohm ?

CC3220SF SOP2 current is critical ?

Hi Lishen,

Yes, on your custom board, you can use a 100k ohm for the pull down on SOP2.

Dear Seong,

Why? How do you know our application?

How to evaluate resistor value for SOP2 ?

Best Regards,

Hi Lishen,

I do not know your application. I just meant that while a 2.7k is used on our reference design, it is safe to use a 100k instead.

BR,

Seong
