Abstract: An infrared circuit for a single battery and a remote controller using the same are provided. The single battery outputs a battery voltage. The infrared circuit comprises an IR LED circuit, an inductor and a microcontroller. The IR LED circuit is coupled between the battery voltage and a common voltage. The inductor is coupled between the battery voltage and the common voltage. The microcontroller has an I/O port coupled to the inductor and the IR LED circuit. When infrared rays are emitted, the microcontroller controls the battery voltage to charge the inductor through the I/O port, and a continuous current of the inductor forces the IR LED circuit to turn on.

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.
