ABSTRACT:
An apparatus for providing power control to a real-time clock oscillator is disclosed. The apparatus includes a clock oscillator, a set of current limiting resistors and a set of latches. The current limiting resistors are coupled between a power supply and the clock oscillator. Coupled to the clock oscillator and the current limiting resistors, the latches control the current limiting resistors to limit the amount of current flowing from the power supply to the clock oscillator such that the power consumption by the clock oscillator is minimized.
