摘要 PCT No. PCT/JP95/02657 Sec. 371 Date Aug. 27, 1996 Sec. 102(e) Date Aug. 27, 1996 PCT Filed Dec. 25, 1995 PCT Pub. No. WO96/20457 PCT Pub. Date Jul. 4, 1996An integrated circuit card control circuit includes a clock control circuit for receiving a control signal, delaying the received control signal by a first delay time, and outputting the delayed control signal as a clock control signal. A delayed signal generating circuit receives the control signal, delays the control signal by a second delay time which is longer than the first delay time, and outputs the delayed control signal as a delayed signal. A power supply control circuit outputs a power supply control signal in response to one of either the control signal or the delayed signal, and a reset control circuit outputs a reset control signal in response to both the control signal and the delayed signal.
