s32k118 sleep mode

[종찬박]

Hi,

I'm Jongchan.

Let me ask you question about sleep mode for S32k118.

First, I need to output in sleep mode.

For example, Before sleep mode, the board turn on LED. and then After Sleep mode, it have to remain LED on.

so, Do I have to select only VLPR mode to implement above case? Isn't there any thing else?

(in datasheet, VLPR mode consumes more 1 mA. I have to satisfy lower current under 0.5mA)

Second, How do I configurate to wake up via CAN communication?

I refer to AN5425(Power Management for S32K1xx). but there is not How to configurate wake-up source.

I want you to get me the code like AN5425 example source.

Third, What is the function "scg_disable_pll_and_firc()"?

could you show me the code of function "scg_disable_pll_and_firc()" that is in 5.5.2 of the AN5425?

Thanks,

BR,

Jongchan

Hi Jongchan,

Input / Output (I/O) states are maintained during all power modes.

About how to wake up via CAN communication, you can refer below articles:
Example S32K116 FlexCAN PN STOP S32DS.ARM.2.2
Example S32K116 FlexCAN VLPR test S32DS.ARM.2.2
S32K1xx SDK FlexCAN sample projects to demonstrate its basic and advanced features

Best Regards,
Robin

Hi Robin,

thanks for your response.

I'm developing my application with using low level peripheral driver even CAN Communication.

So, I need the function "scg_disable_pll_and_firc()" code. then, I would be able to clear my problem.

could you send me?

And, considering the consumption current, I have to use the VLPS mode.

But the example you sent is the project usint the SDK. so I couldn't use your example.

could you send me the low level code using VLPS via CAN wake up?

Best Regards,

Jongchan.

Sorry for the late reply!
I can not find the function "scg_disable_pll_and_firc()" code either.
Please refer to the similar function code in the SDK
POWER_DRV_DisableVlpClockSrc
