English: Die size: 6.5 x 6.0 mm The MC68030 is a second-generation full 32-bit enhanced microprocessor from Motorola. The MC68030 is a member of the M68000 Family of devices that combines a central processing unit (CPU) core, a data cache, an instruction cache, an enhanced bus controller, and a memory management unit (MMU) in a single VLSl device. The processor is designed to operate at clock speeds beyond 20 MHz. The MC68030 is implemented with 32-bit registers and data paths, 32-bit addresses, a rich instruction set, and versatile ad- dressing modes. It retains the flexible coprocessor interface pioneered in the MC68020 and provides full IEEE floating-point support through this interface with the MC68881 or MC68882 floating-point coprocessor. Also, the internal functional blocks of this microprocessor are designed to operate in parallel, allowing instruction execution to be overlapped. In addition to instruction execution, the internal caches, the on-chip MMU, and the external bus controller all operate in parallel.
