Method and apparatus for enabling a stand alone integrated circuit

A stand-alone integrated circuit (IC) comprises:

• a reset circuit operable to place the stand-alone IC in an idle state until a supply lock signal is enabled;
• an on-chip power converter that generates a supply from an external power source upon assertion of a power enable signal;
• and
• supply lock circuit operably coupled to enable the supply lock signal when the supply substantially reaches a steady-state condition.

A stand-alone IC comprises:

• on-chip power converter;
• processing module;
• and
• memory operably coupled to the processing module, wherein the memory includes operational instructions that cause the processing module to:
• establish an idle state that holds at least a portion of the stand-alone IC in a reset condition when a power source is operably coupled to the stand-alone IC;
• receive a power enable signal;
• enable, in response to the power enable signal, the on-chip power converter of the stand-alone IC to generate at least one supply from the power source;
• and
• when the at least one supply has substantially reached a steady-state condition, enable functionality of the stand-alone IC.
