Abstract
Abstract Complementary pad and pin configurations are provided for the pads of a system board receptacle (20) and the pins of alternative first and second IC packages (15,25) to be inserted in the receptacle. The system board accommodates multiple power supplies. The system board receptacle is constructed with a pad configuration having a first power supply pad and trace (VCCA) for coupling to a first power supply, and second and third power supply pads and traces (VCCB1,VCCB2) for coupling to a second power supply. A first IC package is constructed with a pin configuration for a first IC package (15) requiring multiple power supplies includes a first power supply pin (VCCA) coinciding with the first power supply pad and trace of the system board receptacle and a second power supply pin (VCCB1) coinciding with the second power supply pad and trace for supplying portions of the integrated circuit of the first IC package from different power supplies. The first IC package is formed with a third no-connect pin coinciding with a third power supply pad and trace (VCCB2) of the system board receptacle 20. A second IC package pin configuration includes a single power supply pin (VCCB2) coinciding with the third power supply pad and trace of the system board receptacle (20). The second IC package pin configuration is constructed without pins coinciding with the first and second power supply pads and traces (VCCA, VCCB1). Complementary ground pads and pins are also provided. The first and second IC packages may be used interchangeably in the same system board receptacle (20) without modification of the system board.
