while maintaining MC68000 target code compatibility.

By combining the superscalar performance of the MC68060 with a wide range of optional features and the IndustryPack interface, OEMs can customize the MC68060 for their applications.

OEMs can choose the right product for their application without having to pay for features they don’t need.

The new “Petra” application-specific integrated circuits (ASICs) replace features previously implemented in the IP2 chip, MC2 chip, and MCECC chip, improving the performance of the memory subsystem.

Memory configuration switches enable customers to customize memory sizes for applications requiring smaller memory configurations.
