I. Product Overview

The MVME5500 is the highest-performance flagship SBC in the VME bus history, a comprehensive upgraded version of the MVME5100. It focuses on military, aviation, radar, high-speed signal processing, semiconductor equipment, 1GHz PowerPC, AltiVec vector, dual PMC + dual PCI, gigabit network, wide temperature resistance, long-term supply (now EOL, replaceable).

Original manufacturer: Motorola → Emerson → Artesyn → Abaco

Core positioning: The strongest computing power in a single-slot VME, the preferred choice for data-intensive applications

Architecture: PowerPC 7457 (G4) + Marvell system controller + dual independent PCI buses
