The Current Specification of the integrated RTC of a Intel Atom processor E3800 family is regarding the datasheet defined as follows:
See atom-e3800-family-datasheet.pdf , Rev 1.0, Page 106
Is there a more detailed specification of the typical and the max. current of the RTC? Have someone measured the typical and the max. current of the RTC?
We need a backup battery lifetime of >8 years and with 100uA RTC current a backup battery with 7Ah is needed! This is not acceptable.
