CC1350STK: CC1350STK current consumption in standby mode

Part Number: CC1350STK
Other Parts Discussed in Thread: CC1350

Hi,

I noticed that, cc1350STK consumes approximately 0.3 mA in standby mode. When i connect devpack onto it and re-mesure, the consumption drops to appoximately 0.1 mA but it is still high.

I also test with cc1350 launchpad and the current consumption is normal and around 1-2 uA in standby mode.

I disabled all pin configs in BoardGpioInitTable for both cc1350STK and launchpad. I used the pinStandBy_CC1350STK and pinStandBy_CC1350_LAUNCHXL examples for STK and Launchpad respectively.

Could you please explain such a high standby current consumption in CC1350STK? Why current drops when i connect devpack onto cc1350STK? Is there any current leakage even i disable all pin configs in BoardGpioInitTable?

Kind Regards,

Alper

    Hi Alper

    On the sensorTag there are several sensors and an external flash that must be set in "sleep" from the application to be able to get the data sheets numbers for the current consumption. The LP also has an external flash that needs to be disabled. How this is done, you can see in the rfWsnDmNode example.
