Integrated circuit with on-board power utilization information

An electrical system comprising:

• an integrated circuit that comprises:
• a first module that operates to store power utilization information for at least a portion of the integrated circuit, the power utilization information comprising information of at least one preferable power supply characteristic for electrical power provided to the integrated circuit;
• and
• a second module, communicatively coupled to the first module, that operates to perform communication comprising at least one of:
• transmitting the power utilization information to an electrical device external to the integrated circuit;
• and
• receiving the power utilization information from an electrical device external to the integrated circuit;
• wherein the information of at least one preferable power supply characteristic is based, at least in part, on a power supply characteristic monitored during production testing of another integrated circuit having preferable power supply characteristics for electrical power provided to the another integrated circuit that are similar to preferable power supply characteristics for electrical power provided to the integrated circuit, and
• a power supply circuit that comprises:
• an interface module, communicatively coupled to the second module of the integrated circuit, that operates to perform communication comprising receiving the power utilization information from the second module of the integrated circuit;
• and
• a power output module that operates to provide electrical power to the integrated circuit, where a characteristic of the electrical power is based, at least in part, on the power utilization information.
