The Motorola MC68030 is a 32-bit microprocessor in the Motorola M68000 Family, the successor to the 68020. Later members include the 68040 and 68060.
The internal architecture was similar to the 68020; performance was increased in part by the increased use of caching; the MC68030 included an additional separate 256-byte cache for data.
It was the first family member to include memory management on the main chip. It did not include floating point; a separate floating point chip had to be used if hardware floating point was desired.
It was used in a number of Macintosh, Amiga and later Atari personal computers, and also workstations from NeXT.
Downgraded versions which omitted the memory management were produced.
