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, which can be found on the congatec AG
website at www.congatec.com.

Humidity
Operation: 10% to 90%
Storage: 5% to 95%
Caution
The above operating temperatures must be strictly adhered to at all times. When using a heatspreader the maximum operating temperature
refers to any measurable spot on the heatspreader’s surface.
congatec AG strongly recommends that you use the appropriate congatec module heatspreader as a thermal interface between the module
and your application specific cooling solution.
If for some reason it is not possible to use the appropriate congatec module heatspreader, then it is the responsibility of the operator to ensure
that all components found on the module operate within the component manufacturer’s specified temperature range.
For more information about operating a congatec module without heatspreader contact congatec technical support.
Humidity specifications are for non-condensing conditions.
