Abstract
A dual protocol input device for use with a host system is provided. In one embodiment, the input device comprises a chip with a number of semiconductor devices integrally formed thereon, including: an optical navigation sensor (ONS) to sense movement of the ONS relative to a surface; a wired protocol block to communicate data from the ONS to the host system by a wired communication protocol; a wireless protocol block to communicate data from the ONS to the host system by a wireless communication protocol; and a micro-controller coupled to the ONS, the wired protocol block and the wireless protocol block, to switch the input device between the wireless communication protocol and the wired communication protocol.
