Microcontrollers are one of the main digital components that we cover in Electronic Design. Or at least that's the way it was when I played with things like the Intel MCS-48/8748. These days microcontrollers have artificial-intelligence (AI) accelerators built in. Bluetooth and other wireless technologies are in the mix as well as specialized units for motor control. In any case, I wanted to see how many companies are still around and what they do, hence the Microprocessor and Microcontroller Companies page.
