680x0

                                                                                                 68000
Manufacturer Motorola
Category 16-bit microprocessor
Introduction 1979
History

Got its name since it has about 68000 transistors on a chip; during its introduction the 68000 was the best microprocessor by a wide margin;
responsable persons: - Daniels / Stein: Overall 68000 Project
                                - Tom Gunter: processor architecture
                                - Gene Schrier: development of circuits
the 68000 was implemented in one of the best known minicomputers: Apple MacIntosh; thus it became as successful as the 8086 / 8088; in opposite of the 8086 / 8088 which were the leading CPUs in personal computer market the 68000 became the most used CPU for industrial and work station applications (powerful graphic features)

Technology

HMOS technology; first advanced 16-bit microprocessor with a 32-bit internal architecture and the first with 16 Mbyte nonsegmented direct memory addressing;

Max. clock frequency

12 MHz
