Choosing and Using 4-bit Microcontrollers

This work sets out to simplfy the process of selecting the right microcontroller that will fit the needs of a given system, so paving the way for efficient and cost-effective design. Information is given on which 4 bit microcontrollers are available from which manufacturers, and the strengths and limitations of each supplier are covered. "choosing a 4 bit microcontroller": examines how 4 bit microcontrollers are used, detailing a case study that illustrates the methods employed to manage peculiarities of a particular chip; outlines which products and systems are suitable with 4 bit microcontrollers, covering medical, industrial, educational and entertainment devices; and explains how a variety of commonly-required system features can be implemented, considering hardware and software aspects of the design process.
