What might appear a relatively straightforward task can turn into an all- encompassing exercise as the designer conducts deeper analysis of SoC datasheets

from the first page of each data sheet, it pays to conduct a more thorough analysis covering everything from transceiver power consumption, the number of and operation of deep-sleep modes,


and the availability of soſtware stacks and tool chains. An industry benchmark profile further adds structure to this comparative analysis and avoids any costly misunderstandings.
