Abstract: This paper outlines the general principles and practical methods in dealing with design and implementation of low powerconsumption system. The MCS-51 family single chip microcomputer is used as a special case. A circuit scheme of power supply controllingas well as programming of low power consumption systems are also introduced forwards at the end of the paper.
