Q: Typically, does the MCU have a higher power requirement than the CPU?
A: Most MCU manufacturers don't specify the power drawn by the CPU alone. Perhaps you mean does a microprocessor draw more power than a microcontroller? Yes, usually. a high-end Pentium-class MCU needs a heat sink. MCUs do not.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
