Note
There is a limitation with the Intel
®
Platform Controller Hub EG20T and the RTC. The RTC leakage current is extremely high. This means the
RTC battery within a system featuring this chipset will be depleted after as little as 8 months.
congatec solves this RTC current leakage problem by using the onboard board controller found on the conga-QA6. When the conga-QA6 is
powered off, the EG20T RTC is disconnected and the onboard board controller’s RTC is used. When the conga-QA6 is restarted, the BIOS
overwrites the EG20T system clock with the correct one provided by the congatec board controller.
