MC68060RC50 Description

The superscalar MC68060RC50 represents a new line of NXP? Semiconductors microprocessor products. The M68060 product line consists of the MC68060, MC68LC060, and MC68EC060. The MC68060 is fully equipped with a floating-point unit (FPU) and a memory management unit (MMU) for high-performance embedded control applications. For cost-sensitive embedded control and desktop applications where an MMU is required, but the additional cost of an FPU is not justified, the MC68LC060 offers high performance at a low cost. Designed explicitly for low-cost embedded control applications, the MC68EC060 eliminates both the FPU and MMU, permitting designers to leverage MC68060 performance while avoiding the cost of unnecessary features.
