CC3100: HOSTINTR pull-down value

ScanLabs

Part Number: CC3100

Hi,

reference design suggest to apply a 10Kohm pull down resistor to avout tany false interrupt during the Boot/Init phase .

In order to save power during normal activity it is possible to move this value to 47K or even 100Kohm ?

Hi Paolo,

My apologies for the delay. You can use 100K if the interrupt line is not connected to any FDI chip. The 10K value on our board is due to that line being connect to FDTI.

Thanks,

Riz
