ABSTRACT:
A microcomputer for driving a resonant circuit includes a CPU for processing data, an input circuit for detecting an input signal and for transmitting it to the CPU, an output circuit for outputting an output signal from the CPU to the resonant circuit, and attenuation device for attenuating oscillation in the resonant circuit after the output signal from the CPU is turned off. In a non-contact IC card the resonant circuit is an antenna for sending and receiving data to and from the outside without contact.
