S32K3 Power Mode STANDBY

kjy106906 — Mon, 23 May 2022 01:18:42 GMT

Hello I have questions about S32K3 Standby mode.

I saw the link and tested the S32K312 STANDBY RTC Wakeup. https://community.nxp.com/t5/S32K/S32k344-Rtc-wake-up/m-p/1318132#M11543
However, it is reset when STANDBY -> Wakeup.
Can I know the cause?
What does the abbreviation for SOC in SOC_STANDBY mean?

Hi Junyeong,
Most of the chip is reset on standby exit. Only the modules in STANDBY domain are not impacted by standby exit and retain their content. The device starts booting from standard reset handler, it does not continue executing the code where you entered standby.
I’m not sure why SOC_STANDBY was used, I can’t see reason for that. Just consider this as a normal STANDBY.
Regards,
Lukas

Power_Ip_SetMode STANDBY cannot lower the current consumption of S32K3.
However, Soc prepare standby -> Soc Standby lowers the current consumption.

So I use Soc Standby
