Product Summary
The MC68040RC33V is a Motorola’s third generation of M68000-compatible, high-performance, 32-bit microprocessor. The device is virtual memory microprocessors employing multiple concurrent execution units and a highly integrated architecture that provides very high performance in a monolithic HCMOS device. The MC68040RC33V integrates an MC68030-compatible integer unit (IU) and two independent caches. The device contains dual, independent, demand-paged memory management units (MMUs) for instruction and data stream accesses and independent, 4-Kbyte instruction and data caches.
