hello team,

we are using FS26 SBC in our designs. we planning to wake up the SBC using below configuration.

Wake1:

the wake1 pin of SBC will be high when the external enable (BECM) is high and LDO output is LOW.

Wake2:

the wake2 pins is connected to reset pin of uC (S32K312)

can please confirm whether this strategy is correct or not??

Hello,

I hope all is great with you. Thank you for using the NXP communities.

I do not see any issue with the logic. As we know, the WAKEx pins can detect wake-up event on high level or low level.

Please make sure you configure the correct event detection polarity on the WAKEx pins.

Anyway, I do recommend to perform you own tests before any conclusion.

I hope this information helps.

Regards,

David
