METHOD AND APPARATUS FOR PROGRAMMABLY PROVIDING A POWER SUPPLY VOLTAGE TO AN INTEGRATED CIRCUIT.

The invention relates to programmable voltage regulator that programmably provides a desired operating voltage to a power pin based upon operating voltage configuration data. The programmable voltage regulator includes an operating voltage configuration data decoder arranged to decode the operating voltage configuration data. The programmable voltage regulator also includes a programmable voltage down converter connected to the operating voltage configuration data decoder. The programmable voltage down converter uses the decoded operating voltage configuration data to convert the first voltage to the desired operating voltage which is then output to the power pin.
