MVME2400
Product Description
The MVME2400 is a rugged, VMEbus-compliant single-board computer engineered to deliver reliable, high-performance embedded computing in extreme operating environments. Building on the legacy of Motorola’s MVME series, it addresses key pain points of general-purpose SBCs—such as limited environmental resilience, insufficient processing power for real-time tasks, and rigid I/O integration—by combining industrial-grade components, flexible expansion, and robust communication. Its core value lies in three pillars:
- Ruggedized Design: Withstands extreme temperatures, vibration, and shock, complying with military/aerospace standards (e.g., MIL-STD-810H) for uninterrupted operation in oil rigs, aircraft test systems, or steel mill control rooms.
- High-Performance Processing: Equipped with a PowerPC CPU (a hallmark of later MVME models), it delivers 100+ MIPS of computing power, supporting real-time operating systems (RTOS) like VxWorks or QNX for latency-sensitive tasks (e.g., PID control loops, high-speed data filtering).
- Versatile Integration: Features a 32-bit VMEbus interface (IEEE 1014-1995) for seamless expansion with I/O modules, communication adapters, or storage units. On-board I/O (serial, Ethernet, parallel) enables direct connection to sensors, actuators, and HMIs, reducing system complexity.
Typical applications include:
- Real-time control of industrial machinery (e.g., turbine governors, robotic assembly lines)
- Data acquisition and processing in aerospace test equipment (e.g., flight simulators)
- Mission-critical computing in defense systems (e.g., ground-based radar data processing)
