CMOS Battery Power Consumption1.6.1

RTC @ 20ºC Voltage Current

Integrated in the Intel

I/O Controller Hub

82801FBM (ICH6M)

3V DC 2.49 µA

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 specic 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.

Environmental Specications1.7

Temperature Operation: 0° to 60°C Storage: -20° to +80°C

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 specic 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 specied temperature range.

For more information about operating a congatec module without heatspreader contact congatec technical support.

Humidity specications are for non-condensing conditions.
