1. Product Overview

MVME55006E-0163R is the top-tier rugged wide-temperature VME single board computer from Motorola/Emerson MVME5500E series, targeted at high-reliability real-time embedded computing applications. The MPC7457 1GHz PowerPC with AltiVec vector engine delivers powerful floating-point and signal processing performance, ideal for radar data processing, aerospace flight control, railway signal interlock and heavy industry DCS master control. Dual independent 64-bit PCI buses and dual PMC expansion slots provide flexible scalable I/O expansion without sacrificing system bandwidth; dual gigabit Ethernet ensures redundant high-speed network communication for critical control loops. Full conformal PCB coating and -40~+85°C wide temperature rating enable stable operation in severe outdoor, vehicle, shipboard and explosion-proof cabinet environments. Built-in ECC error correction memory prevents data corruption caused by industrial radiation interference; long-life battery-backed NVRAM preserves configuration and fault log data during full power loss. Hot-swappable design supports online replacement without shutting down the entire VME rack, minimizing system downtime for uninterrupted production/mission equipment. Compatible with mainstream real-time OS VxWorks and embedded Linux, equipped with MOTLoad standard boot firmware for convenient on-site commissioning and debugging.
