Abstract: An information processing device for independently generating power without receiving independent power from the outside is provided to facilitate manufacture of the information processing device and prevent power consumption generated from a terminal when the information processing device is not used. An interface offers a means for transmitting/receiving a clock signal and a data signal with an external device. A clock generator(265) generates a clock having a predetermined cycle from the clock signal inputted from the external device through the interface. A power generator(270) generates the independent power from the clock signal inputted from the external device through the interface.

Abstract: PURPOSE: A low-power smart card and a controlling method thereof are provided to reduce entire power consumption of the smart card by stopping the rest unnecessary hardware in the smart card when only the specified module performs the needed operation such as a password operation and a data I/O(Input/Output) operation. CONSTITUTION: An I/O module(100) outputs a state signal according to an operation state. A logical sum gate(140) performs the logical sum for the state signal provided from the I/O module. Inverting-logical multiplication gates(150,160,170) perform the logical inversion multiplication for the logical summed state signal and a system clock. A CPU(110), a password operation module(120), and a random number generator(130) respectively receive an inverting-logical multiplied clock signal from each inverted logical multiplication gate.
