Do you have an idea for an electronic product, the next must-have gadget, music or video system, time saver, or greatest problem-solving device that was ever invented? Even if you have the electronics product design expertise available, there are a number of tasks that you must complete and issues that you must resolve before you have an actual product design that can be produced, marketed, and sold. Once you have completed a product specification document and a marketing study, you should be prepared to have the product electronics and packaging design processes begun so that a prototype unit can be assembled and tested.
One of the first choices that must be made in the electronics design is which microprocessor or microcontroller architecture will be utilized if your product idea requires processing capability. Most microprocessor or microcontroller devices are available in a variety of configurations of internal memory sizes with some including non-volatile Flash memory for program storage, quantity and types of input and output pins, package types for surface mount or thru-hole applications, clock speeds, and interfaces that are supported by the processor without having to add additional devices.
