The Motorola 68000 is a 16-bit microprocessor with internal 32-bit architecture and buses, introduced in 1979.
It requires +5 V power only and came initially in 64-pin DIL packages. The external bus is asynchronous.
The 68000 has non-multiplexed data (16 bit) and address (24 bit) buses. The 68008 was a version with an 8-bit external data bus, initially available in a 48-pin DIL package. The 68010 (1982) included minor improvements to support virtual memory and virtualization.
The data ALU is 16 bits wide.
Initial speed grades were 4, 6 and 8 MHz. Faster versions and CMOS implementations were available later, as were second-source versions.
