Device and Method for Selectively Controlling the Utility of an Integrated Circuit Device

摘要

A radio frequency controller device is provided that enables the utility of an integrated circuit (IC) device using an RF communication. The radio frequency controller device has a switch that is set to a defined state responsive to the RF communication. More particularly, conditional logic circuitry uses the RF communication to determine if the IC's utility should be changed, and sets the state of the switch accordingly. The radio frequency controller device also has an IC interface that allows the IC to determine the state of the switch, and based on the state of the switch, a different utility will be available for the integrated circuit device. The radio frequency controller device also has an antenna for the RF communication, as well as a demodulator/modulator circuit.
