CC3200 power consumption in hibernate mode

Luca Maestri

Other Parts Discussed in Thread: CC3200, CC2500

Using the "hib" example of the CC3200 SDK, in hibernation mode I measured ~20 uA. Documentation says that should be 4 uA but in this number is not included the flash memory consumption. Can I shut down the flash using the Power Management Framework? How?

Thanks

Hi LM,

Could you invoke Utils_SpiFlashDeepPowerDown(); before MAP_PRCMHibernateEnter(); and share your results?

This API (Utils_SpiFlashDeepPowerDown) places the SFLASH in deep power down mode.

Best regards,

Naveen

I've tried your hint and I got a current measure of ~10 uA in Hib mode (half than before). The multimeter is not so accurate, so...I think it should be the better I can obtain. Thank you so much!

I didn't find this API (Utils_SpiFlashDeepPowerDown) anywhere in the latest CC2500 SDK. Where is it?

Thanks,

Patrick.

Err... I meant CC3200 SDK. Sorry!

Hi Patrick,

You will find it in cc3200-sdk\example\common\utils_if.c in the cc3200 SDK 1.0.

Best regards,

I have an early Launchpad board (V3.2) and an early silicon version XCC3200HZ. I measure a current of 40uA with the flash in low power mode. Is this expected?

Thanks,
