Comparison with Competitors

In the VMEbus SBC market, the primary competitors to Motorola were Force Computers, PEP Modular Computers, and other embedded computing manufacturers.

• MOTOROLA MVME162-012 vs. Force Computers SPARC/68K Boards: Force offered competing 68K and SPARC-based boards. The MOTOROLA MVME162-012 benefited from Motorola’s own processor technology and a vast ecosystem of software and support, making it a preferred choice for many OEMs.
• MOTOROLA MVME162-012 vs. PEP Modular Computers: PEP offered compact VME solutions. The MVME162-012 provided a more full-featured, integrated solution with onboard SCSI and Ethernet, often reducing the need for additional modules.
• MOTOROLA MVME162-012 vs. Contemporary PC/104 Solutions: While PC/104 offers a different form factor, the MOTOROLA MVME162-012 excels in applications requiring the robustness of the VME backplane, superior cooling in sealed enclosures, and long-term supply guarantees that standard PC components may not offer.

Selection Recommendations and Precautions

1. Processor and Memory Verification: The MOTOROLA MVME162-012 may have different variations. Confirm the specific processor speed (e.g., 25MHz vs. 32MHz) and the amount of installed DRAM to ensure it meets your application’s processing and memory requirements.
2. Operating System and BSP: When using the MVME162-012, ensure you have the appropriate Board Support Package (BSP) for your chosen RTOS (e.g., VxWorks, OS-9). This is critical for hardware abstraction and driver support.
3. IndustryPack Modules: If your application requires specialized I/O, verify the availability and compatibility of IndustryPack modules for the MOTOROLA MVME162-012.
4. Environmental Specifications: Ensure the MVME162-012 variant you select meets the environmental requirements (temperature range, coating) of your target application, especially for military or outdoor installations.
