The 6800 family of 8-bit microprocessors (µPs) and microcontrollers (µCs) is based upon the Motorola 6800 CPU. The architecture also inspired the MOS Technology 6502, and that company started in the microprocessor business producing 6800 replacements.
The chips primarily competed against Intel's 8-bit family of chips (such as the 8080, or their relations, the ZiLOG Z80 range).
