LPO Frequency deviation - RTC scalling | S32K146

Hi all,

I have question regarding LPO frequency in S32K146, I couldn't find any details about thermal compensation and frequency deviation during run-time.

I'm obligated to use LPO oscillator in RTC unite - it's only way during VLPS(without external oscillator 32, 768 kHz).

In case of big frequency fault (~10%) I will use LPO trimming but I want to know - how the system works while temperature changes.

Another question is the best practices during automatic RTC scaling before entering LPO mode, if you have any working way, please share it.

Thank you in advance, Jan
