Abstract:
1. An integrated circuit comprising: a package including a first package-substrate connection, a second package-substrate connection, and metallization coupling the first package-substrate connection to the second package-substrate connection, wherein the package is a flip-chip package; and a substrate electrically and physically coupled to the package via the first package-substrate connection and the second package-substrate connection, the substrate comprising a plurality of power domains and a power control unit, the second package-substrate connection of the package coupled to a particular power domain of the plurality of power domains, the power control unit comprising logic and a switch, the switch including a first terminal coupled to a voltage supply terminal, a control terminal coupled to the logic, and a second terminal coupled to the first package-substrate connection of the package, the logic to selectively activate the switch to distribute power to the particular power domain via the metallization of the package wherein the substrate is encapsulated in the package.
