CMOS Battery Power Consumption

The CMOS battery power consumption value listed above should not be used to calculate CMOS battery lifetime. You should measure the
CMOS battery power consumption in your customer specific application in worst case conditions, for example during high temperature and high
battery voltage. The self-discharge of the battery must also be considered when determining CMOS battery lifetime. For more information about
calculating CMOS battery lifetime refer to application note AN9_RTC_Battery_Lifetime.pdf on congatec AG website at www.congatec.com.
Note
The CMOS battery consumption of the conga-TC87 revision C.x and earlier draw significantly high current as shown in the table above. This
is due to the fact that the PM_PCH_PWROK signal on revision C.x and earlier is not terminated to ground.
This issue will be corrected with conga-TC87 hardware revisions D.x and later. Contact congatec technical support department for more
information about this topic.
