Hi Team,

 

I am working with atsamc21j18A,we want to keep this microcontroller in sleep mode ,unless someone will press the power button .

There is no reference for samc21 current consumption ,

 

When I kept for sleep mode ,mcu was showing 2-8mA it is varying not constant also .

 

So I just want to ask ,

1)What will be the current consumption before sleep mode and after sleep mode(stand by)?

2)Why I am getting 2-8mA even if in sleep mode ? 

 

Thanks,

Smruti

1. "45.7 Power Consumption" is in the datasheet. Also 92 other occurrences of "Power Consumption" in there.

2. You need to configure io, clocks and peripherals to reduce power consumption before going to sleep.
