The '''Motorola 68040''' is a [[microprocessor]] from [[Motorola]], released in [[1990]]. It is the successor to the [[68030]] and is followed by the [[68060]] (the 68050 was an abandoned project and never shipped, the 050 was to the 040 what the 030 was to the 020, a simple die shrink and cache size increase - although the 030 did incorporate a MMU unit that the 020 lacked). In keeping with general Motorola naming, the 68040 is often referred to as simply the ''040''. The stripped-down version of the 68040 that lacks the FPU is the [[Motorola 68LC040|68LC040]].
In [[Apple Macintosh|Macintosh]] computers, the 68040 was found mainly in the high-end [[Macintosh Quadra|Quadra]]s. The fastest 68040 processor was clocked at 40 MHz and it was only used in the Quadra 840AV. The more expensive models in the (short-lived) mid-high [[Macintosh Centris|Centris]] also used the 68040, while the cheaper Centris and [[Macintosh Performa|Performas]] used the [[Motorola 68LC040|68LC040]]. The 68040 was also used in other [[personal computers]] such as the [[Amiga 4000]], as well as a number of [[Workstation]]s and later versions of the [[NeXT]] computers.
