Abstract
A plurality of voltage generating circuits forming a voltage generator system on a chip are controlled by a centralized voltage generator control arrangement. The voltage generator control arrangement includes a controller with a state machine (52) that receives control signals from various devices on the chip as, for example, a clock generator, voltage detectors, bondpads, testpads, fuses, and predetermined registers. From the received signals, the controller generates control signals to the plurality of generating circuits of the voltage generator system and other circuits on the chip in accordance with a predetermined program sequence for each phase of operation required by the generating circuits to provide the necessary stable voltages to circuits on the chip.
