About the current consumption under RTC operation

Dear All,

 

We want to calculate the life of a Back-up battery when using i.MX6 with RTC 32k X'tal.

 

The datasheet has two descriptions about it.

=> http://cache.freescale.com/files/32bit/doc/data_sheet/IMX6SDLCEC

 

Though described as 41uA in IMX6SDLCEC Page 30, Is it this?

Or should it calculate from the description in Page38? (4uA + 20uA + 1.5uA)

 

Best Regards,

George
