Selecting the proper microcontroller unit (MCU) is one of the critical decisions that controls the success or failure of your project. There are many criteria to consider when choosing an MCU, and this article serves to enumerate most of them. In reviewing the MCU selection process, you must attach your own grading scale to the selection criteria and then evaluate the total to make the right personal decision.

The main goal is to select the MCU that minimizes the overall cost of the system while still fulfilling the system specification (e.g., performance and reliability). The cost includes everything: engineering research and development, manufacturing (parts and labor), warranty repairs, updates, field service, upward compatibility, ease of use, and so on.ote
