Abstract
A device having battery-save circuitry includes a power-on reset circuit (,), an OR-gate (,) coupled to the power-on reset circuit (,), a current-boost timer circuit (,) coupled to the OR-gate (,), a reference oscillator (,) with a start-up current mode enabled by the current-boost timer circuit (,), and a low current secondary reference oscillator (,). A method of operating the device includes operating the device in a battery-save mode and an active mode. A first clock signal is used as a microprocessor clock signal while operating the device in the battery-save mode, and a second or third clock signal is used as the microprocessor clock signal while operating the device in the active mode.
