MVME147-010 MOTOROLA dual-height VME module

MVME147-010—02


Core Advantages:


  1. Processor Performance and Architectural Advantages
    • High-Efficiency 32-Bit Processor:
      Equipped with an MC68030 processor (16/25/33MHz), combined with on-chip cache and a complete Memory Management Unit (MMU). Compared to processors without cache or MMU (such as the early 68020), data processing efficiency is improved by 20%-40%. It supports virtual memory and software protection mechanisms, making it suitable for multi-task real-time systems.

    • Floating-Point Calculation Capability:
      Standard with an MC68882 floating-point coprocessor, supporting the IEEE 754 standard. In scenarios requiring high-precision floating-point operations (e.g., scientific computing, signal processing), it significantly outperforms similar modules with pure integer arithmetic.


  2. Rich Communication Interfaces and Expandability
    • Multi-Serial Port Design:
      Provides 4 EIA-232-D serial ports and 1 printer port, supporting simultaneous connection of multiple peripherals (e.g., sensors, human-machine interfaces, modems). Its expandability far exceeds competitors with only 1-2 serial ports.

    • High-Speed Data Transmission:
      Integrates SCSI bus interface (supporting DMA) and Ethernet interface, enabling high-speed data exchange with storage devices (e.g., hard drives) and local area networks. In contrast, some contemporary modules only support low-speed parallel interfaces or lack network functionality.

    • VMEbus Compatibility:
      As an A32/D32 VMEbus master/slave device, it supports system controller functions, seamlessly integrating into complex VME multi-module systems. It is compatible with Motorola and third-party VME modules (e.g., I/O cards, communication cards), protecting users' initial investments.


  3. Reliability and Stability Design
    • Industrial-Grade Specifications:
      Operating temperature range: 0°C–55°C (with forced air cooling), supporting wide voltage input (typically 24VDC). Adopting anti-vibration design and industrial-grade components, it adapts to harsh industrial environments, with a Mean Time Between Failures (MTBF) significantly higher than commercial-grade modules.

    • Redundancy and Fault Tolerance Mechanisms:
      Built-in watchdog timer and battery-backed SRAM clock prevent system crashes and preserve critical data during power outages. Compared to modules without backup designs, it is more suitable for critical applications requiring continuous operation (e.g., power monitoring, aerospace testing).

    • Memory Protection:
      DRAM supports programmable parity checking, detecting and correcting single-bit errors to enhance data transmission reliability. Some competitors only offer memory configurations with no parity or fixed parity.

    • MVME147-010—01

  4. Software Development and Debugging Convenience
    • Integrated Debugging Tools:
      On-board debugger/monitor firmware (e.g., ROM-based debugger) supports online code debugging and system diagnostics, eliminating the need for additional hardware debuggers and reducing development costs.

    • Multi-System Support:
      Compatible with real-time operating systems such as UNIX SYSTEM V/68 and VMEexec, providing complete driver packages. This significantly shortens the development cycle compared to modules requiring self-developed underlying drivers.

    • Standardized Programming Interfaces:
      Following POSIX standard APIs, it offers strong code portability, facilitating migration from other platforms or integration with third-party software.

  5. Cost-Effectiveness and Long-Term Support
    • Modular Design:
      Users can configure memory capacity (4–32MB DRAM) and processor speed (16–33MHz) as needed, offering greater cost-effectiveness than competitors with fixed configurations.


Differentiated Value in Application Scenarios

  • Aerospace Testing: Floating-point computing capability and multi-serial port design suit high-speed data acquisition and real-time simulation.

  • Power System Monitoring: Watchdog timer and memory parity ensure continuous operation reliability, while VMEbus compatibility facilitates integration into distributed control systems.

  • Industrial Robot Control: MMU supports multi-task isolation, and high-speed Ethernet interfaces meet real-time communication needs.



With its balanced performance, reliability, and expandability, the MVME147-010 held a significant position in the industrial control field from the 1990s to the early 2000s, especially for complex systems sensitive to costs and requiring long-term stable operation.
