Key Features The MVME162PA-344SE delivers industrial-grade reliability through dual-port SRAM with battery backup, real-time clock persistence, and configurable memory addressing. Modular IndustryPack expansion enables plug-and-play integration of analog, digital, and specialized I/O functions. Optional SCSI and Ethernet connectivity support networked data acquisition and storage architectures without external interface cards.

Typical Applications Process control systems, distributed data acquisition platforms, industrial automation controllers, VME-based test systems, and embedded real-time signal processing requiring deterministic timing and high-bandwidth I/O.

Compatibility & Integration Full VMEbus compliance ensures integration into existing VME backplane systems. Optional MVME712 Series Transition Modules adapt the P2 connector for standard industrial I/O connectors. Alternative MC68LC040 processors (without FPU) are available for cost-sensitive variants.
