Emerson / Motorola MVME162-13 Embedded Controller

The Emerson/Motorola MVME162-13 is a double-high VME embedded controller built on the MC68040 enhanced 32-bit microprocessor for industrial control and data acquisition in harsh environments. This single-board computer delivers system controller functionality with configurable memory, multiple communication interfaces, and four IndustryPack® expansion slots - each with dedicated DMA channels for real-time I/O processing.

Key Features

Dual-port serial architecture with user-selectable protocols

Battery-backed SRAM for non-volatile variable storage across power cycles

Four independent IndustryPack® DMA channels eliminate CPU bottlenecks in multi-sensor systems

VMEchip2 integration reduces external logic and improves reliability

Optional Ethernet and SCSI reduce board count in networked or storage-intensive systems

Typical Applications

Industrial process control and real-time monitoring

High-reliability data acquisition with long-term power-loss data preservation

VME-based test automation and instrumentation

Multi-interface embedded systems requiring deterministic I/O timing

Compatibility & Integration Full VMEbus master/slave operation enables integration into existing VME crates. IndustryPack® modularity supports third-party I/O modules without custom development. Configurable DRAM (1–8 MB) and optional Ethernet/SCSI accommodate variable system requirements.
