A method for microcontroller design was developed. A basic data path configuration capable of processing the microcontroller basic instruction set was developed first. Based on this configuration, a four-bit microcontroller was developed from its most basic instruction set to the most complex one. Through the design process, the microcontroller hardware evolves into a complex one as more instructions are added to the basic instruction set. More hardware is added in parallel to the basic data path configuration to make the execution of more complex instructions possible. As a result it is expected that readers become familiar with the fundamental microcontroller concepts and operations. Design steps, implementation and testing of all the microcontroller development circuits are shown graphically and explained in detail. Finally designers will have a basic guide to develop their own microcontroller using this work procedure.
