Where Have All the Microcontrollers Gone?

Each company product page has links to the plethora of products sold by the company. For some, like Texas Instruments or Renesas, the list is massive, but it does give you an idea of the breadth of their product lines. The links take you to their websites so you can drill down.

I find this information useful as products from a particular vendor are often integrated only in app notes. Some tend to take things to extremes, since integrated development environments (IDEs) have added configuration and software frameworks to the mix.

You many also notice the Articles and Parts Direct links on each page. The Articles link goes to the Electronic Design company page that has a list of the articles and multimedia contents associated with the company. Hopefully, many are listed on their individual pages, since we have covered most of these companies for decades. However, some have fewer as these pages are relatively new and not all of the articles are properly linked. Going back and fixing those takes time. Thus, the latest articles are usually in the list.

Parts Direct is a sister site that features lists of distributors, manufacturers (like our company list) and products so you can find and order products. You may have your favorite distributor already, but they may not have all the parts you need for a project.

Finally, I added a section, where appropriate, that lists companies acquired by a company. In many cases, the list is long and infamous. Ever wonder what happened to Freescale or Signetics? Some of you may not even know of these companies. Its some fun trivia. These lists aren't exhaustive.

Did I miss anyone? Did I miss a product category? Probably. More likely definitely.

I'm sure I'll be getting a few emails from product managers and public relations companies with additions and corrections, so this list may eventually reflect all of reality. In the meantime, I hope you find something useful or interesting from these lists. These aren't AI generated, but the companies are forever changing and the lists are curated by real people.

I'll probably add lists for other categories like FPGAs in the future. If you have any preferences, let me know. I didn’t know what I would find when I started this particular list on processors and it's a lot longer than I imagined. Also, keep in mind that I was only looking for vendors with standard components versus specialized or custom products. Given fabless companies that utilize someone else’s foundries, the list could be even longer.
