A wireless communication terminal with a power delay function is provided to prevent a power-on of the terminal by an external force rather than by a user's intention by delaying a time taken to apply a power using a power delay circuit (e.g., capacitor having a large capacitance value). The invention comprising a power transfer unit for providing a switch-on signal to a controller in response to a power-on switching signal from the outside and dividing a voltage of a driving power transferred from an external power supply, a power delay unit for delaying the driving power from the power transfer unit, a power loop hold unit for holding a power loop based on a power hold signal from the controller and the driving signal from the power delay unit, a power apply unit for converting the power from the power supply into a constant voltage in accordance with the driving power from the power loop hold unit and applying the converted constant voltage to the controller, and the controller driven in response to the constant voltage from the power apply unit for providing the power hold signal to the power loop hold unit in response to the switch-on signal from the power transfer unit. |
