I am new to microcontrollers, and am in the process of designing a prototype of what I hope to be a commercial device. I have narrowed down the choices of microcontroller, and so far the best choice seems to be the Freescale M68HC08 family, because of low-cost and power, and up to 4K RAM. I should mention that I am at a university. What I don't know is the life-cycle of microcontrollers...
