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.
## Technical Specifications
**Microprocessor**
• MC68040 32-bit core running at 25 MHz or 32 MHz

• High-performance D64 burst DMA for VMEbus and local memory
**Communication & Expansion**
• Two serial ports: EIA-232-D console + configurable EIA-232-D/EIA-422/EIA-530 user port
• Optional Ethernet interface (Intel 82596CA controller) with 32-bit DMA
• Optional SCSI interface (NCR53C710 narrow SE controller) with 32-bit burst DMA
• Four IndustryPack® slots (16- or 32-bit) with dedicated DMA channels
**Timers & Monitoring**
• Six 32-bit programmable timers (four available without VMEbus interface)
• Integrated watchdog timer
**Physical & Environmental**
• Double-high VME form factor: 233.4 mm height × 160.0 mm depth

• Humidity: 5% – 90% RH (non-condensing)
• Power: +5 V DC (±5%) at 3.5 A typical/4.5 A max; ±12 V DC (±5%) at 100 mA max
• Typical power consumption: 15 W
## 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.
