The Motorola 68030 is a 32-bit microprocessor in Motorola's 68000 family. Released in 1987, the 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040. In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced oh-thirty).
The 68030 features an on-chip split instruction and data cache of 256 bytes each. It also has an on-chip memory management unit. The 68881 and the faster 68882 F...

The Motorola 68030 is a 32-bit microprocessor in Motorola's 68000 family. Released in 1987, the 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040. In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced oh-thirty).
The 68030 features an on-chip split instruction and data cache of 256 bytes each. It also has an on-chip memory management unit. The 68881 and the faster 68882 FPU (floating point unit) chips could be used with the 68030. A lower cost version of the 68030, the Motorola 68EC030, was also released, lacking the on-chip MMU. It was commonly available in both 132 pin QFP and 128 pin PGA packages, but the poorer thermal characteristics of the QFP package limited it to 33 MHz and below; the 40 MHz and 50 MHz only usually being available as PGA, though there was a small supply of QFP packaged EC variants.
As a microarchitecture, the 68030 is basically a 68020 core with an additional data cache and a process...
