Abstract
An IC for communication includes a single oscillating circuit, which is capable of flexibly dealing with the change of data rate or data processing load, and is produced at a low cost and consumes low electric power. In the IC for communication, a frequency multiplying circuit( ) is inserted between the output of an oscillating circuit( ) and a micro-controller circuit( ), or a frequency dividing circuit( ) is inserted between the oscillating circuit( ) and a data receiving circuit( ). A receiving address is stored in a dual port RAM( ). Further, by controlling a receiving frequency of synchronous codes, battery saving efficiency is increased.
