Material Composition Premium military and aerospace-grade components. 256MB DRAM from highest-reliability suppliers. Redundant signal path design on critical PCB traces. Military-specification gold-plated connectors with maximum durability rating.
Structural Characteristics 6U VME standard form factor. Enhanced IEEE 1101 front panel with heavy-duty handles. Advanced LED diagnostic system. P2 connector for MVME761. DRAM mezzanine connector for expansion flexibility.
Working Principle The 233 MHz MPC750 accesses 256MB ECC DRAM through high-bandwidth memory controllers. The 1MB L2 cache optimizes frequently accessed data. The full VME64 interface supports maximum system throughput. The board maintains single-slot operation even with PMC expansion.
Installation Requirements Highest-reliability VME64 chassis with excellent thermal management. Redundant power supply strongly recommended. Verify chassis can deliver sufficient current for 256MB memory configuration.
Usage Notes 256MB provides maximum capacity for the most demanding applications. Regular ECC monitoring is essential. Ensure proper documentation for military or aerospace deployments. Maintain strict battery replacement schedules.
