Abstract:
A wireless keyboard array integrated circuit (IC) device uses a wireless keyboard array IC to simultaneously conduct code transmission and receiving the decoding as well as output the signal data keyed in from the keyboard to a keyboard controller by the method of serialization and via the emitting circuit and receiving circuit, then the keyboard controller transmits the signal data into a compute; the said wireless keyboard array IC comprises:an oscillation circuit controls the initiation of the enable signal by the keyboard to makes the circuit generate operation; a first transmission/receiving circuit conduct the transmission or the receiving of the signal data keyed in at the keyboard; an array detector detects the signal data transmitted from the first transmission/receiving circuit; a signal processor, via the data transmission rate circuit and identifier, distinguishes and processes the signal data detected by the array detector; a coder codes and transmits the signal data distinguished and processed by the signal processor to a second transmission/receiving circuit and then to the receiving circuit via the emitting circuit; a decoder receives, decodes and then transmits the coded signal data of the receiving circuit via the second transmission/receiving circuit to the signal processor for distinguishing and processing; an array decoder further decodes and then transmits the decoded signal data distinguished and processed by the signal processor via the via the data transmission rate circuit and identifier, to the keyboard controller through the first transmission/receiving circuit.
