Note
1. Do not use the CMOS battery power consumption values listed above to calculate CMOS battery lifetime.
2. Measure the CMOS battery power consumption in your customer specific application in worst case conditions (for example, during high
temperature and high battery voltage).
3. Consider also the self-discharge of the battery when calculating the lifetime of the CMOS battery. For more information, refer to application
note AN9_RTC_Battery_Lifetime.pdf on congatec GmbH website at www.congatec.com/support/application-notes.
4. We recommend to always have a CMOS battery present when operating the conga-PA5.
