MC68040RC40A Description

The MC68040RC40A is Motorola's third generation of M68000-compatible, high-performance. 32-bit microprocessor. The MC68040RC40A is a virtual memory microprocessor employing multiple concurrent execution units and a highly integrated architecture that provides very high performance in a monolithic HCMOS device. It integrates an MC68030-compatible integer unit (IU) and. two. independent caches. The MC68040RC40A contains dual, independent, demand-paged memory management units (MMUs) for instruction and data stream accesses and independent, 4-Kbyte instruction and data caches.
