Abstract
The present invention relates to an apparatus and a method for transferring a data signal between a smartcard interface and an interface of a processor within an embedded system. According to an exemplary embodiment of the present invention, an interface conversion device communicating between a processor and a smartcard IC chip includes: an input/output signal conversion logic configured to transfer a signal between a first interface of the processor and a second interface of the smartcard IC chip; a clock generator configured to generate a clock signal driving the smartcard IC chip depending on a first control signal received from the processor and provide the generated clock signal to the smartcard IC chip; and a reset controller configured to generate a reset signal depending on a second control signal received from the processor and provide the generated reset signal to the smartcard IC chip.
