e14 Question of the Month

We're interested in finding out what considerations are most important to you when choosing a microcontroller. Take the poll and let us know, and please tell us why in the Comments section below!

  • There are many factors that influence your selection.

    Most important are requirements and cost of the development capability.

    Back when I was doing embedded systems, the cost of the development system often drove the selection, though not always.

    The company wanted to standardize on one processor family, but we kept pointing out that the one they wanted to use would not meet the customers requirements.

    I had forgotten how expensive those early development systems were - astronomical for a starving student.

    I was in school around 2000. One of our professors sold an 8051 "dev board" for $99. It had the processor, RAM, ROM, and RS-232 interface. It was only large enough to fit all of those chips.

    At the time, I could not believe such an incredible piece of development hardware was so cheap! It was almost 10X cheaper than anything else I could buy.

    (Fortunately, at the time, I could use the educational license of Keil, so that took the IDE out of the price discussion.)

    Today, if you charged me $100 for a development MCU board, I would expect the packing material to be dollar bills. (Joking, but only slightly.)
