The 68h family of 8-bit microprocessors (µPs) and microcontrollers (µCs) is based upon the Motorola 6800 CPU. However, more companies than Motorola produced or innovated on the design—the foremost among those companies being MOS Technology and the Western Design Center.

The chips primarily competed against Intel's IA-8 family of chips (such as the 8080, or their relations, the ZiLOG Z80 range).
