Hello. NXP Team.

 

I have a problem that I can not get low current in VLPS Mode.

Now I am using s32k118. And I did check below s32k datasheet.

s32k118 --> 26uA or 38 uA

 

So. I refer to below link

S32K144EVB-Q100 VLPS current 

 

And I added below code.

* Disable UART in doze mode

* Disable FIRC, SOSC

* PMC->REGSC  CLKBIASDIS = 1

* PMC->REGSC  BIASEN = 1

 

But the Board is measured 20mA. I want to get a lower current(26uA).

Is there anything else I need to do?

 

Thank you.

Best regards.

 

MinYeop.
