Motorola MVME5101-0131 | VMEbus Single Board Computer 500 MHz

Description Product Introduction VMEbus systems don’t die—they just need faster processors. The MVME5101-0131 drops into any standard VME chassis and brings a 500 MHz PowerPC 750 to the backplane. It’s a workhorse board for legacy industrial control, military, and telecom gear that needs more horsepower than the old 68K chips could deliver. The “0131” suffix tells you exactly what you’re getting: 500 MHz CPU, 256 MB SDRAM, and no mezzanine. In my experience, this is the sweet spot for most retrofits—enough memory to run VxWorks or Linux, but not so much that you’re paying for unused capacity. The board includes two Ethernet ports, two serial ports, and one PMC slot for expansion. Rock-solid, runs forever, but when they fail, finding a replacement gets harder every year.

Firmware Version: Look for PPCBug 1.5 or later. Earlier versions had issues booting from CompactFlash adapters and some PMC cards. v1.5 added support for larger flash devices and fixed PCI enumeration bugs. Compatibility: Works with any VMEbus chassis and backplane Compatible with MVME5100 series PMC modules For VxWorks, you need the appropriate BSP (board support package) Configuration: Access PPCBug via serial terminal at power-up. Commands include: env show — display current environment set — change boot parameters probe — scan VMEbus and PCI devices boot — boot from specified device Upgrade Process: Firmware updates require a flash image file and either: A serial connection and XMODEM transfer, OR A bootable floppy/CD with the update utility Download the .bin file from Emerson/Artesyn (if available) Connect serial terminal at 9600 baud Use PPCBug commands to erase and reprogram flash Verify checksum and reboot Rollback: You can downgrade to earlier PPCBug versions if needed. Keep a backup of the original image before upgrading. Compatibility & Replacement Matrix Use this when maintaining or upgrading VMEbus systems. Original Model Replacement Model Compatibility Level Key Notes MVME5101-0131 MVME5101-0131 Drop-in Identical part. Direct replacement. MVME5101-0131 MVME5100-0131 Drop-in MVME5100 is the base model. The -0131 suffix is the same configuration (500 MHz, 256 MB). Direct replacement. MVME5101-0131 MVME5500-0161 Needs Adaptation MVME5500 is a newer generation (7455 CPU). Faster, more memory, but VMEbus compatible. May require OS/BSP updates. MVME5101-0131 MVME2600 Incompatible MVME2600 is a much older 68K-based board. Won’t run PowerPC code. MVME5101-0131 Third-party VME SBC Needs Adaptation Possible, but requires driver/BSP development and testing. Not a drop-in.
