Product Introduction
Motorola MVME5100 is a 6U VME single board computer built on the PowerPlus II architecture, using PowerPC MPC7400 or MPC750 processors. It executes embedded control applications and acts as the main CPU inside VME chassis, with dual PMC mezzanine slots to add custom I/O or communication hardware.
This SBC includes ECC memory, watchdog timer, and battery-backed real-time clock. The onboard VME controller lets it act as VME system controller or slave, while dual Ethernet and serial ports provide external host and field device connectivity.

Application Scenarios & Field Experience
Part 1 (Narrative Paragraph)
Legacy VME-based control systems depend on stable single-board processors for continuous operation. Component aging can trigger memory errors or boot failures that halt the whole rack. The MVME5100 uses ECC SDRAM and watchdog reset logic to mitigate transient memory faults in high-vibration industrial environments.
Part 2 (Numbered List)
- Semiconductor wafer processing tools: Run VME-based motion and recipe control inside photolithography and etch equipment.
- Aerospace test benches: Execute closed-loop simulation and data acquisition for aircraft component qualification rigs.
- Railway signaling control racks: Handle real-time logic and data logging in legacy VME train control systems.
- Nuclear balance-of-plant monitoring: Serve as supervisory processing node for legacy safety-related data collection racks.
Part 3 (Short Field Story)
A semiconductor fab’s old VME processing rack crashed randomly during long wafer runs. The original SBC developed uncorrected memory corruption under thermal cycling. After installing a tested MVME5100 with fresh battery and validated ECC memory, boot cycles and recipe execution stayed consistent. The tool ran full production batches without unplanned stops for six months.
Standard Operating Procedure (SOP) for Quality Control
- Visual & Origin Inspection: Inspect PCB, VME P1/P2 connectors, front panel switches, OEM labeling and serial numbers. Check for corrosion, solder rework, and validate OEM markings for anti-counterfeit screening.
- Live Rig Testing: Install board in 6U VME test chassis, apply rated power, verify boot sequence and front panel LED status. Validate VME bus enumeration.
- Firmware & Boot ROM Verification: Read and log boot firmware revision. Record version in test report for OS and application compatibility review.
- Peripheral Functional Test: Test ECC memory, flash read/write, dual Ethernet, serial ports, watchdog timer and NVRAM/RTC battery function.
- ESD-Safe Packaging: Seal board inside static shielding bag, secure with foam inserts inside rigid carton. Include signed QC test certificate with shipment.
Frequently Asked Questions (FAQ)
Q1: What operating systems and PMC cards work with the MVME5100? A: It supports VxWorks, Linux, and other PowerPC embedded operating systems. It accepts standard 32/64-bit PMC mezzanine cards. Confirm boot firmware version, OS BSP, and PMC pin mapping before ordering.
Q2: What warranty is included for this module? A: We offer a 12-month warranty. Warranty covers hardware defects. It does not cover damage from ESD, battery leakage, incorrect VME backplane voltage, or corrupted flash firmware.
Q3: Do you hold stock of MVME5100 and what is the shipping timeline? A: We maintain limited inventory of new surplus and refurbished units. Most fully tested units ship within 1–3 business days after QC approval. Confirm stock status through our website before procurement.
Q4: Can boot ROM mismatches cause failed board initialization or VME bus errors? A: Yes. Outdated boot firmware can prevent memory initialization, break PMC detection, or create VME bus arbitration faults. We supply firmware revision records for every shipped unit.
Q5: Can I hot-swap this VME SBC while the VME chassis remains powered? A: Do not hot-swap this 6U VME SBC on a live powered rack. Removal under power damages the VME backplane and connected modules, and will abort all running application logic. Power down the chassis fully before replacement.
