Abstract

See full text

In a non contact IC card for generating a power supply voltage from electric waves transmitted via wireless communication from a base unit, a reset signal generating circuit is provided to reset the internal circuits when the power supply voltage rises to a predetermined operating voltage and when it is lowered below a minimum voltage of voltages which ensure the normal operation of the internal circuits, thereby operations such as a writing operation in the internal circuits can be made stable and the time required for communication can be shortened.
