Zusammenfassung:	PURPOSE: An electronic control unit for a smart key system having a single constant voltage device is provided to include the single device and two micro-control units, thereby effectively securing the starting property of the system. CONSTITUTION: An electronic control unit for a smart key system having a single constant voltage device includes a main micro-control unit (100), a sub micro-control unit, a latch circuit (400), and the constant voltage device (300). The main micro-control unit and the sub micro-control unit are mutually resettable. The latch circuit secures the starting of a vehicle. The latch circuit is supplied with the 12V power of a battery, and then is driven. The device drops the 12V power into a voltage power at a certain level. The device supplies the power to the main micro-control unit and the sub micro-control unit. [Reference numerals] (AA) IGN 1,2 RLY output
