Product Introduction
Motorola MVME8105 serves as a high-reliability embedded computer for demanding automation tasks. This SBC delivers precise control using dual-core processing.
The Motorola MVME8105 runs at 2.0GHz with 4GB ECC memory. It handles heavy data loads reliably. Non-volatile storage prevents data loss during power failures.

Quality Control Process
We test every board rigorously. First, we verify the 2.0GHz P5020 boots correctly. Next, we run memory diagnostics on the 4GB DDR3 ECC RAM. We check the 512KB MRAM retention too. Serial and Ethernet ports get loopback tests. Finally, we pack units in anti-static shielding.
Replacement Pitfall Guide
❗ Watch the VxWorks Version. Bootloaders vary by release. Mismatches cause hard failures. Verify your BSP first.
❗ Check Backplane Power. Dual-core chips draw significant current. Ensure your chassis supplies adequate 3.3V and 5V rails. Undervoltage causes random resets.
❗ Thermal Management Matters. This SBC runs hot under load. Verify airflow direction matches chassis design. Overheating throttles the 2.0GHz core quickly.
❗ MRAM Initialization. The 512KB MRAM retains data without power. However, new boards need formatting. Don’t assume it is ready immediately.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level (Direct/Needs Adaptation) | Migration Notes |
|---|---|---|---|
| MVME8105 (Same Rev) | Direct | Verify firmware revision matches exactly | |
| MVME8105 (Newer Rev) | Needs Adaptation | Check pinout changes on P1/P2 connectors | |
| MVME8100 Series | Needs Adaptation | Requires chassis and BSP modifications |
- Processing Benchmark: Sustained 2.0GHz dual-core throughput for real-time control loops
- Memory Bandwidth: 1333MHz DDR3 ECC ensures data integrity during high-speed I/O scanning
