Abstract
A radio frequency identification integrated circuit for reducing pin counts and an RFID providing method thereof are provided in the present invention. The radio frequency identification integrated circuit includes a first IO pin, a second IO pin and a third IO pin. The method includes determining whether the coil is coupled to the first IO pin, the second IO pin and the third IO pin when the RFID IC is enabled; and determining the identification according to the voltage status of the non-coupled pin and the pins coupled to the coil.
