I am running the MCU at 1/4/8MHz (using the internal 8MHz oscillator with all other oscillators disabled, except the internal 32KHz oscillator ) and measuring the current consumption in normal run mode. It is consuming 0.43/1.2/2.2mA respectively which I find much higher than what the datasheet specifies.
I set up the project in Atmel Studio 7.0 using Atmel Start project, set the clock to the mentioned frequencies and ran my code. I am not using any peripherals for now.
I read the Application note regarding reducing power consumption but I couldn't find anything that reduced the run mode power consumption with no peripherals running.
What am I missing? Why is the power consumption much higher than the datasheet?
