Key Features The MVME104 provides a foundation for systems requiring flexible memory expansion through dedicated socket configurations. The combination of DRAM and socket-based SRAM/EPROM/RTC support enables rapid customization for application-specific requirements. Dual-access DRAM supports concurrent processor and I/O operations, reducing bus contention in multi-master VME environments.

Typical Applications Industrial control systems, data acquisition platforms, and communication infrastructure leverage this board's master-capable architecture. The modular memory and interface design suits OEMs deploying UNIX variants and proprietary operating systems across process automation, monitoring, and telemetry roles.

Compatibility & Integration The MVME104 integrates into VMEbus ecosystems, supporting standard backplane interconnects and crate architectures. Operating system compatibility includes UNIX variants and proprietary monitors, enabling deployment across heterogeneous embedded environments. Memory flexibility and bus mastery make it suitable for multi-board configurations requiring coordinated I/O and real-time processing.
