Description
The Emerson (formerly Motorola) VME172PA652SE is a high-performance single-board computer (SBC) designed for the VMEbus architecture. It belongs to the VME172 series, which integrates a powerful MC68060 microprocessor with specialized VME interface logic. This module is engineered for real-time industrial applications that demand high-speed processing and deterministic performance. The “PA” designation typically refers to a specific configuration including VME64 support and enhanced onboard memory management, making it a staple for high-end control systems.

Application Areas
The VME172PA652SE is utilized in specialized industrial and defense environments, such as:
- Aerospace Systems: Flight simulation and cockpit instrumentation control.
- Semiconductor Tools: Precision motion control for wafer processing and lithography.
- Power Distribution: High-speed data acquisition for electrical grid monitoring.
- Automated Testing: Serving as the central controller for complex ATE (Automated Test Equipment) racks.
Product Instructions
The VME172PA652SE must be installed into a standard 6U VMEbus backplane. Before insertion, ensure the system power is off and that you are wearing an ESD-safe wrist strap. The module should be carefully aligned with the guide rails and pushed firmly until the DIN connectors are fully seated. Once powered, the onboard “PPC” or “Stat” LEDs will indicate the initialization progress. Configuration of the VME address space and interrupt levels is typically managed through the Motorola 172-Bug or MOTLoad firmware environments. For communication, the front panel DB-9 ports allow for direct console access to the operating system (e.g., VxWorks or OS-9).
Frequently Asked Questions (Q&A)
Q: Can I use this module to replace an older VME162 or VME167 board? A: Yes, the VME172 series was designed as an upgrade path for the VME162/167, offering higher clock speeds and the more powerful 68060 processor while maintaining compatibility with many VMEbus applications.
Q: What does the “SE” suffix indicate? A: In Emerson/Motorola part numbers, “SE” often signifies a specific software enablement or an “Enhanced” hardware version with additional onboard I/O or specialized logic for industrial signaling.
Q: Is the MC68060 processor still supported? A: While the processor is legacy hardware, it remains widely used in long-lifecycle industrial and military applications. Support is primarily found through specialized industrial electronics distributors and repair centers.
