Hi @Wobaffet 

The minimum boot time is different due to various configurations, so you need to test it according to your own needs.

Sleep time, you can refer to https://www.nxp.com/webapp/Download?colCode=AN13054

Hello Harvey,
Our projecet will be HMI display, so based on this what is your guess about boot time?
Also what is the status of VDD_1v8 and VDD_3v3 outputs of the PMIC at suspend mode, are they 0V?
Thank you in advance!
Best Regards

Hi @Wobaffet 

There is no way to guess, is this displayed from uboot or kernel? The suspend mode depends on how it is defined, whether it is ks0 or ks1, VDD_1V8 and VDD_3V3 KS0 is powered off, and KS1 is not powered off. For details, you can check the link I sent you earlier.

Best regards

Hello,

In our application, to exit sleep mode, I will use K15 ignition pin to wake-up the device. Should I connect the K15 pin to pmic wake-up pin using zener diode? To enter sleep mode I'd like to have software shutdown after ignition is off is it possible?

Best Regards
