Motorola 68040

(processor)
(MC68040) A microprocessor from Motorola. It was the successor to the Motorola 68030 and was followed by the Motorola 68060.

The 68040 was the first 680x0 family member with an on-chip FPU. It also had split instruction and data caches of 4 kilobytes(?) each. It was fully pipelined, with six stages.

The 68040 was used in the Apple Macintosh Quadra series of personal computers.

The MC68LC040 is an MC68040 without a built-in FPU, and the MC68EC040 is an MC68040 without an MMU or FPU.
