RE: Choosing the right MCU or MPU for your design

As is common with short articles of this kind one of the most important factors is not mentioned - the scale or planned production volume.

I work on projects where the planned production volume may be 1 (as in a special purpose tester), a few hundred or, occasionally a few hundred thousand.

At the low volume end the cost of development will be far greater than the cost of parts so an important concern is familiarity, it will be far cheaper to design with a part you or your company has used before and has tools (and maybe code) for.

Only at the high volume end will the choice be driven almost entirely by the component itself -and even then 'political' considerations like preferred suppliers may come into play.

There is a comment in 7 with which I would very strongly disagree - in my experience there is no such thing as a free lunch and a "complete tool set" is a very big lunch indeed. A complete tool set will come with a price tag (which may be HUGE if you include things like Model Based Design) , it won't all come form the processor supplier and it won't be free.

NXP has an Automotive MCUs and MPUs Product Map to ease finding and selecting the right Microcontroller or Microprocessor for your industrial and automotive design. Its latest version includes both software and hardware enablement, covering most of the above insights!

Check the Automotive MCU and MPU Product Map and avoid unnecessary MCU/MPU hurdles!
