DMA+ADC IN VLPS mode

[YASHAY]

Hi,

can i use DMA+ADC  on S32K116 micro in VLPS mode ?

reading some documents it seems you can use but it does not give me the option on S32K Power estimation tool ?

need some guidance.

Thanks.

Thanks for the reply.

so in order to use ADC+DMA for minimum power consumption , i have to change power mode every time?

in RUN mode using only ADC and DMA what could be the typical current consumption do you have any idea ? 

Thanks

Yes, ADC is not available in VLPS, so you need to change the mode. I don't know current consumption for this exact use-case, I can only recommend "Table 13. Power consumption" in the datasheet and Power Estimation Tool to get some boundaries what to expect.

Hi @YASHAY 

you can take a look at "Table 39-4. Module operation in available power modes" in the reference manual:

It says that ADC is turned off in VLPS mode:
