单片机系统的低功耗运行是实现袖珍型实用器具节能的关键。本文从芯片选择、芯片待机状态运行、晶振振荡频率选取、程序、数据存储器的合用以及外围电路控制等方面论述了单片机系统低功耗运行的可行性,并应用于语音报时器,获得满意效果。
The low-power operation of the microcontroller system is the key to saving energy for pocket-sized utility appliances. This article discusses the feasibility of low-power operation of the single-chip microcomputer system in the aspects of chip selection, chip standby operation, crystal oscillator frequency selection, program, data memory combination and peripheral circuit control and so on, and is applied to the voice timer to obtain satisfactory results.
