Selecting the right MCU for a project is not easy. Functionality, price per unit, power consumption, footprint, development environment and costs, 3rd-party support and long-term availability are just a few considerations to be made.
A $300 industrial grade quad-core Intel i7-7xxx PC or a $0.30 PIC10F200? It all depends on the use-case. In any project where performance is more important than price, the selection is easy. But, when more than 1.000 units are needed, price do matter. And in most non-consumer products, longevity really matters. Some products might be in production in 10 or even more years, and spare MCU boards are needed even longer.
Let’s go through some options - excluding the embedded PC market.
