Four-slot IndustryPack logic interface for embedded monitoring and control applications
The MVME172P4 allows VME embedded controller users to achieve the price-performance value of RISC architectures while maintaining MC68000 object code compatibility. By combining the MC68060 superscalar perfor- mance with a wide range of optional features and the IndustryPack interface, OEMs can select the exact product for their application rather than paying for unwanted features.
The inclusion of the new “Petra” application-specific integrated circuit (ASIC), which replaces functions formerly implemented in the IP2 chip, MC2 chip, and MCECC chip, improves the performance of the memory subsystem. Memory configuration switches enable the customer to tailor memory size for applications requiring smaller memory configurations.
