Abstract
A portable data device (400) having a power controller (430), a clock generator (428) and a digital circuit (432). The power controller (430) has an output signal. The output signal is representative of available power. The clock generator (428) is coupled to the output signal of the power controller (430) for generating a variable clock rate corresponding to the output signal. The digital [ath0228]circuit (432) is coupled to the clock generator (428), and the digital circuit (432) is controlled by the variable clock rate.
