I measure a power cunsumption of about 2-3 uA without RTC when ti uC is in LLS-Mode ( measured on J4, FRDM-KL25Z ). As soon as I have the RTC running the current consumption is about 23-24 uA. I see in the datasheet that I_RTC should be between 432 and 810 nA - much smaller then 20 uA. If I dont have the RTC-Clock connected to PTC1 the current consumption is ok even if the RTC-Module is enabled.
Does anyone know what is wrong here?
Thank you for any hint .. Dominic
