Re:Exploring DynamIQ and ARM’s New CPUs: Cortex-A75, Cortex-A55 by pja on Monday May 29, 2017 @07:17AM (#14438541)
Eg, the processor in the BBC MicroBit pulls about 10mA @ 2.5V or so. Of course, it only runs at 32MHz or so & has a whopping 16kbit of RAM, but you can run one off a pair of AA batteries for a week or two without ever sleeping.
