Motorola 68008 (MC68008) microprocessor belongs to the first generation of 68000 microprocessors. The 68008 is fully object-code compatible with the 68000, but not pin-compatible with it. The 68008 has 8-bit data bus, and, depending on packaging, it may have 20-bit or 22-bit address bus. Because the processor has smaller address and data buses, it doesn't require as many signal pins as the 68000 microprocessor and could be manufactured in smaller packages:
  • The 68008 microprocessor in 48-pin ceramic or plastic DIP package can address up to 1 MB of memory.
  • The processor in 52-pin PLCC package can address up to 4 MB of memory.

Due to smaller size of the data bus the Motorola 68008 needs twice as many fetches to read instructions and data - this makes the CPU slower than the 68000 microprocessor running at the same frequency.
