M68060 User Manual ,

The superscalar MC68060 represents a new line of Motorola Microprocessor products. The first generation of the M68060 product line consists of the MC68060 MC68LC060, and MC68EC060. All three Microprocessors offer superscalar integer performance of over 100 MIPS at 66 MHz. The MC68060 comes fully equipped with both a floating-point unit (FPU) and a memory management unit (MMU) for high-performance embedded control and desk- top applications. For cost-sensitive embedded control and desktop applications where an MMU is required, but the additional cost of a FPU is not justified, the MC68LC060 offers high-performance at a low cost. Specifically designed for low-cost embedded control appli- cations, the MC68EC060 eliminates both the FPU and MMU, permitting designers to lever- age MC68060 performance while avoiding the cost of unnecessary features. Throughout this product brief, all references to the MC68060 also refer to the MC68LC060 and the MC68EC060, unless otherwise noted. By Freescale Semiconductor, Inc
