4. Product Introduction (Anti-Template)
The Motorola MVME5500 is a high-performance 6U VME single-board computer that was positioned as the flagship of the Motorola VME product line at the time of its introduction. It is built around a 1 GHz MPC7455 or MPC7457 PowerPC processor with AltiVec vector processing support, making it suitable for data-intensive real-time applications.
The board provides balanced subsystem performance: 512 MB of on-board PC133 ECC SDRAM (expandable to 1 GB via a memory mezzanine), dual independent 64-bit PCI buses supporting PMC modules at up to 66 MHz, a Gigabit Ethernet interface plus a separate 10/100 Ethernet port, and the Tundra Universe II VME bridge. It remains a single VME slot even when populated with two PMC modules or a memory mezzanine. I/O is designed for compatibility with the earlier MVME51xx family. The MVME5500 was widely used in industrial control, defense, telecommunications, and scientific systems running real-time operating systems such as VxWorks or Linux. Exact processor stepping, memory configuration, and firmware version should be confirmed when sourcing a replacement.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full model number, processor type/speed, memory size, presence of any mezzanine or PMC modules, and firmware/boot labels. Photograph all identifiers and connectors.
- Functional Testing – Install in a compatible VME chassis, apply power, and verify front-panel status, serial console response, Ethernet link, and basic memory operation. Full validation requires the target operating system and application.
- QA & Packaging – Protect P1/P2 connectors, PMC sites, and edge contacts. Clean according to electronics handling practices and pack in anti-static protective packaging with rigid support.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial VME processor boards. Packaging must protect against electrostatic discharge and mechanical shock; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
Memory Mezzanine vs PMC Conflict – The memory expansion mezzanine and PMC slot 1 share physical space; both cannot be installed simultaneously.
Processor Variant – Confirm whether the unit uses the MPC7455 or later MPC7457 stepping, as this can affect software and thermal considerations.
VME System Controller – Only one board in the chassis should be configured as the system controller. Incorrect jumper or firmware settings can cause bus contention.
Firmware / Boot Monitor – Verify the required MOTLoad or other boot firmware version and any application-specific configuration stored in NVRAM or Flash.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified MVME5500?
As a high-performance legacy VME SBC, availability depends on surplus stock. Typical lead time after verification is 5–20 business days plus specialized shipping.
What is the primary function of this board?
It is a high-performance 6U VME single-board computer based on a 1 GHz PowerPC processor with Gigabit Ethernet and dual PMC expansion.
What processor does it use?
MPC7455 or MPC7457 PowerPC running at 1 GHz, with AltiVec support.
How much memory does it have?
512 MB ECC SDRAM on-board, expandable to 1 GB with an optional memory mezzanine.
Does it support PMC modules?
Yes. It provides two independent 64-bit PMC sites capable of 33/66 MHz operation.
Is the board still in production?
No. The MVME5500 is a discontinued product. Units are sourced from surplus and specialist refurbishment channels.
What should be confirmed before ordering a replacement?
Exact processor type and speed, memory configuration, presence of any mezzanine or PMC modules, firmware/boot version, and compatibility with the existing VME chassis and I/O transition requirements.
