The Motorola 68040 Processor
Successor to the 68030 and followed by the 68060 - not 68050. There was no 68050. The even numbers (68000, 68020, 68060) were reserved for major revisions to the 680x0 core. The odd numbers (68010, 68030, 68050) were minor upgrades from the previous chip. For example, the Motorola 68010 was a Motorola 68000 with some minor enhancements and modifications to some user/superuser instruction assignments. The Motorola 68030 was a Motorola 68020 with an MMU and more minor enhancements. The 68050 would have been a 68040 with some bugs fixed, which didn't really warrant a new name so it was sold as a 68040.
 
The 68040 was the first 680x0 family member with an on-chip FPU. It also had split instruction and data caches. It was fully pipelined, with six stages.
 
The 68LC040 is a 68040 without a built-in math coprocessor (FPU), the 68EC040 a 68040 without a memory manager or built-in FPU.
 
It was used in many models of the Apple Macintosh Quadra/Performa series of personal computers, several UNIX workstations and the Commodore Amiga 4000.
