Actually MKE04<SPAN> has no backup power domain and requires the processor to remain powered in a very low leakage state, usually using a low power 32Khz oscillator rather than crystal. That is to say you need to use a low leakage mode instead of power off to keep the processor powered that will keep the RTC data. </SPAN></P></BODY></HTML> Wed, 23 Jan 2019 15:21:29 GMT https://community.nxp.com/t5/MCUXpresso-General/How-to-backup-data-of-RTC-module-MKE04/m-p/887270#M1729 miduo 2019-01-23T15:21:29Z
