Choosing The Optimal Low Power MCU
It is common to normalize the dynamic current to a frequency of 1 MHz and a particular supply voltage. For example, one recently introduced ultra low-power MCU has a dynamic current consumption of 160 μA per MHz at 1.8 V. Without supply regulation, this metric would increase to (160) * (3.2/1.8) = 284 μA per MHz when the supply voltage is 3.2 V.
