The MOTOROLA
VME162PA344SE is a high-performance embedded computer
board designed for industrial-grade embedded systems and mission-critical applications, adhering to the VMEbus (VersaModule Eurocard) standard—a widely adopted open architecture for industrial computing. As a core component of Motorola’s VMEbus product lineup, this board integrates a powerful processor, flexible memory expansion, and multi-protocol communication interfaces, delivering reliable computing capabilities in harsh industrial environments (such as high temperature, vibration, and electromagnetic interference).
Targeted at scenarios requiring long-term stability and high compatibility (e.g., industrial automation control, aerospace testing, and energy monitoring), the VME162PA344SE supports modular expansion via the VMEbus backplane, enabling seamless integration with other VMEbus modules (such as I/O cards, communication cards, and storage cards). Its design emphasizes hardware redundancy, thermal management optimization, and compliance with industrial safety standards, making it a foundational component for building robust embedded control systems.


The MOTOROLA VME162PA344SE is widely used in mission-critical and harsh-environment scenarios due to its industrial-grade reliability and VMEbus compatibility. Key application areas include:
- Factory Automation: Serves as the core controller for large-scale manufacturing lines (e.g., automotive assembly, semiconductor fabrication). It processes real-time data from sensors (temperature, pressure, position) and controls actuators (robots, conveyors) via VMEbus I/O modules, ensuring production efficiency and precision.
- Process Control: Deployed in oil refineries, chemical plants, and power stations to monitor and regulate critical processes (e.g., oil pipeline pressure control, boiler temperature adjustment). Its wide-temperature design and anti-interference capabilities enable stable operation in explosive or high-noise environments.
- Aerospace Testing: Used in aircraft engine test benches and satellite ground control systems. It collects high-speed test data (e.g., engine vibration, fuel flow) via VMEbus high-speed data acquisition modules and performs real-time analysis to ensure test safety.
- Military Embedded Systems: Integrated into military vehicles (tanks, armored cars) and radar systems. Its ruggedized design (shock, vibration resistance) and low power consumption meet the requirements of field operations, supporting tasks like target tracking and communication encryption.
- Power Grid Monitoring: Installed in substation automation systems to process data from smart meters, circuit breakers, and transformers. It communicates with the dispatch center via Ethernet, enabling remote control of power distribution and fault diagnosis (e.g., short-circuit location identification).
- Renewable Energy: Used in wind turbine control systems and solar inverter monitoring. It adjusts turbine blade angles based on wind speed data and optimizes solar power output by coordinating with energy storage systems, improving renewable energy utilization.
- Railway Signaling: Serves as the core computing unit for train control systems (e.g., CBTC). It processes position signals from track sensors and communicates with train-mounted controllers to ensure safe distance between trains and accurate station arrival.
- Marine Control: Deployed in ship navigation and engine management systems. It withstands high humidity and salt spray, monitoring engine speed, fuel consumption, and navigation data to ensure safe and efficient maritime transportation.

- Wide-Temperature & Rugged Design: Operates stably in -40°C ~ +70°C, resisting vibration (10 g) and shock (50 g)—ideal for outdoor or mobile applications (e.g., military vehicles, railway equipment).
- Redundant Power & EMC Protection: Supports dual power input (optional) to prevent system downtime due to single power failure; complies with EN 55022 Class A and IEC 61000-4 standards, avoiding electromagnetic interference with nearby equipment.
- Powerful Processing Capability: The PowerPC 603e processor (up to 300 MHz) and 256 MB SDRAM enable real-time processing of complex tasks (e.g., multi-channel data acquisition, PID control algorithms).
- VMEbus Modular Expansion: Integrates with thousands of VMEbus-compatible modules (I/O, communication, storage) via P1/P2 connectors, allowing users to customize systems without redesigning hardware (e.g., adding 8-channel analog input cards for sensor data collection).
- Extended Product Lifecycle: Motorola provides 7+ years of production support, meeting the long-term maintenance needs of industrial and defense projects (e.g., power plants, military equipment with 10+ year service life).
- Legacy System Compatibility: Supports VMEbus Rev. C.1, ensuring seamless integration with existing VMEbus systems (e.g., upgrading old controllers without replacing the entire chassis, reducing upgrade costs).
- On-Board Debugging Interfaces: The JTAG port enables firmware updates and hardware diagnostics without disassembling the system, reducing maintenance time.
- Flash Memory for Firmware Storage: 8 MB~64 MB flash memory stores bootloader and configuration files, supporting in-system programming (ISP) for remote firmware upgrades (critical for hard-to-access installations like substation cabinets).
