MVME374
Key Features Description
The Motorola MVME374 delivers exceptional processing versatility through its hybrid computing architecture. Its PowerPC 750CXe RISC processor, paired with a high-speed memory controller, enables deterministic real-time performance for time-sensitive applications. The board supports both VME64x and PCI Mezzanine Card (PMC) expansions, allowing integration of specialized I/O modules like analog/digital converters or fiber-optic interfaces.
Advanced system management:
Integrated IPMI 1.5-compliant controller provides remote health monitoring, including temperature, voltage, and fan speed diagnostics. The MVME374 features a hardware watchdog timer and ECC memory protection, critical for unmanned applications in aerospace or energy sectors. Dual Gigabit Ethernet ports with TCP/IP offload engine (TOE) support ensure low-latency network communication, while the modular BIOS allows booting from Flash, network, or removable media.
Designed for high-availability systems, the board offers hot-swap capability compliant with VITA 1.5 standards. Its conduction-cooled variants (available as MVME374-CCC) eliminate fans for silent operation in sealed enclosures. The onboard real-time clock with battery backup maintains system timing during power interruptions, essential for data logging in SCADA systems.
Application Areas
The Motorola MVME374 excels in environments demanding rugged computing solutions. In defense systems, it serves as the core processor for battlefield communications and radar signal processing. Industrial applications include robotic control in automotive manufacturing lines and turbine monitoring in power generation plants.
Key deployment scenarios:
- Railway signaling and traction control systems
- Oil & gas pipeline monitoring (SCADA)
- Air traffic control radar processing
- Medical imaging equipment control
- Semiconductor fabrication tooling
The module’s extended temperature range (-40°C to +85°C) makes it suitable for Arctic exploration equipment and desert solar farms. In telecommunications, its dual Ethernet ports manage base station controllers in 5G infrastructure. The MVME374 also supports legacy VME systems in naval vessels, providing lifecycle extension through modern processor performance.
