Functional Role & Application Analysis
The EMERSON MVME6100-PMCSPAN-MV6100COMI is a heavyweight single-board computer built for the VMEbus architecture. In legacy defense, aerospace, and high-end industrial automation, processing bottlenecks are a constant headache. This SBC solves that problem by packing a 1.267 GHz MPC7457 PowerPC processor and an AltiVec coprocessor into a standard VME slot. It handles massive data throughput and complex control logic without choking the backplane, thanks to its support for the 2eSST VMEbus protocol which pushes bandwidth up to 320 MB/s.
Engineers deploy this board when standard PLCs just don’t have the horsepower:
- Command and Control Systems: Processing high-speed sensor data and radar signals in military ground systems and naval applications.
- Semiconductor Manufacturing: Driving automated test equipment (ATE) and process tools that require extreme computational speed and precise timing.
- Aerospace Avionics: Serving as the central mission computer in reconnaissance or fixed-wing aircraft where rugged, high-density computing is mandatory.
- Legacy Infrastructure Upgrades: Replacing aging VME processors in existing backplanes without having to redesign the entire chassis or rewrite the underlying software.
Our Quality Standard & Testing Process
VME boards are complex, densely packed, and mission-critical. A marginal CPU or a bad PCI-X trace will crash your entire backplane. We don’t just power these up; we stress them.
- Visual & Component Inspection: We inspect the BGA PowerPC processor, DDR RAM, and VME P1/P2 connectors under magnification for cold solder joints, oxidation, or physical trauma.
- Live System Test: The board is seated in a verified VME64 test chassis and run through a continuous 24-hour burn-in to verify thermal stability and backplane power draw.
- Full-Function Diagnostics: We execute MOTLoad firmware diagnostics, verify both Gigabit Ethernet ports negotiate correctly, test the PMC-X slot continuity, and validate the 2eSST VME transfer rates.
- Warranty Backing: Only modules that pass all hardware-level and backplane diagnostics ship with our 12-month warranty. Any board failing memory tests is rejected.

Compatibility & Migration Paths
VME is a strict standard, and mixing hardware revisions can cause backplane faults. Do not guess when deploying this SBC. Verify these points before ordering:
- VME Backplane Generation: Confirm your chassis supports VME64 and the 2eSST protocol. Older VME64x or standard VME backplanes may limit the 320 MB/s transfer rate or require specific jumper configurations.
- PMC Module Compatibility: The dual PMC-X slots support standard PMC and PMC-X cards. If you are adding high-speed I/O, ensure your PMC modules support the 100 MHz PCI-X bus speed.
- Firmware (MOTLoad): Verify your application’s boot sequence matches the MOTLoad firmware revision on this board. Command line parameters and device tree strings are strictly case-sensitive.
- Power Supply Requirements: The MVME6100 draws +5V, +3.3V, +2.5V, and +1.8V. Ensure your VME power supply has sufficient headroom on the +5V rail to handle the 1.267 GHz processor’s startup surge.
