A Low Cost Dedicated Microprocessor Forms the Heart of an Electronic Control System for Appliance Applications

This paper outlines the design concepts and principles of operation of a microprocessor LSI circuit which combines the advantages of electronic control with flexibility allowing a solid state electronic control system to directly compete with the present electromechanical control systems for appliance applications. For this particular study the paper limits itself to discussions around the bulk domestic appliance market i.e. that part made up of clothes washers and dishwashers only, although the same principles are applicable to a wide range of appliance and other applications.
