“While this may seem like a marketing game, developers will ultimately be the winners as vendors refine their techniques for saving power. In the past, a low powered MCU also meant low performance, but vendors have been challenging this correlation by offering increasingly powerful MCUs for low-power applications,” he writes. “Developers, however, faced a problem in evaluating these offerings. Traditional specifications such as operating current in mW/MHz and sleep-mode leakage currents became increasingly difficult to evaluate in the face of the multiple power states that devices offered, and in the face of inconsistency in the industry in the…
