A US corporation originally devoted to the production of car radios. In the late 1950s it entered the semiconductor field and developed the 6800 and 68000 series of processors. These are generally regarded as a better design than the equivalent Intel processor chips and are widely used in embedded systems of all kinds. Motorola later participated in the PowerPC project. It continues to be a major player in the field of mobile communications and related applications such as global positioning systems.
