Emerson / Motorola MVME162-010A Embedded Controller

The Emerson/Motorola MVME162-010A is a VMEbus-based single-board computer engineered for industrial real-time control, data acquisition, and embedded communication systems. Built around the Motorola MC68LC040 32-bit microprocessor, this controller delivers deterministic performance in demanding applications requiring integration with existing VME infrastructure and field I/O expansion.
