Abstract
The invention provides a power supply control system of a singlechip, comprising an internal steady pressure source module, an external steady pressure source module, an awakening key, a power supply control module and a unidirectional conduction module, wherein the internal steady pressure source module is connected with the inner core of the singlechip; the external steady pressure source module is respectively connected with an external power supply and the internal steady pressure source module; the power supply control module is respectively connected with the inner core of the singlechip, the external steady pressure source module, the internal steady pressure source module and the awakening key; and the unidirectional conduction module is respectively connected with the inner core of the singlechip and the external power supply. When the singlechip enters a power saving mode, because the inner core of the singlechip is supplied with a low-voltage power supply, the internal steady pressure source module is instructed to enter a low-power state or closed state, and/ or the external steady pressure source module is instructed to enter the closed state while parts of circuit in the inner core of the singlechip can be maintained to work. Because the internal steady pressure source module and the external steady pressure source module consume certain electric energy when working, the standby power consumption of the singlechip and the whole circuit system can be further lowered after the internal steady pressure source module and the external steady pressure source module are turned off without influence on awakening the singlechip from the power saving mode.
