The NUC100, NUC200, Nano100 and NUC442/NUC472 Series support the RTC controller, but other series do not. The power of RTC controller shares with the power of whole chip for the most chips in NuMicro™ family. Once a chip is powered off, the RTC will work incorrectly when the chip is powered on again.

Nevertheless, the NUC200, M451, NUC505 and NUC442/NUC472 Series have the VBAT pin for supplying the power to RTC to keep it working when the chip is powered off.
