RTC back up mode

Hello. I am developing a project in which I need the real time. Also when de source in turned off. Is there low consuming mode in which I can keep the time even though Vcc is off? I am looking for something similar to what we do when we have an integrated RTC (such as DS1307) in which with a battery the time can be kept.


I am developing with the FRDM KE02 (plus RTC component with the processor expert). If that mode exists, where should the battery be connected?
