MOTOROLA VME172PA-652SE Embedded Controller with IP Slots
MOTOROLA VME172PA-652SE Embedded Controller with IP Slots
Introduction
The MOTOROLA VME172PA-652SE is a high-performance single-board computer (SBC) from the MVME172P2 series, designed for the VMEbus architecture.
This module leverages the superscalar performance of the MC68060 microprocessor, providing a significant performance leap for legacy embedded systems while maintaining object code compatibility with earlier 68K-based controllers.
Featuring two IndustryPack (IP) slots, the VME172PA-652SE offers exceptional modularity, allowing engineers to customize I/O and functional capabilities for mission-critical industrial and defense applications.

Installation and Maintenance
Installation: Align the board with the VME chassis guides and slide it into the slot (Slot 1 is required if the board is the System Controller). Ensure the IndustryPack modules are securely fastened to the board before insertion.
ESD Warning: Always use a grounded wrist strap when handling the module to protect the sensitive Petra ASIC and memory chips from static discharge.
Battery Maintenance: The SRAM and TOD clock rely on an onboard lithium battery. Check the battery voltage during annual maintenance; typical service life is 3–5 years depending on power-off duration.
Cooling: Requires a minimum of 490 LFM (Linear Feet per Minute) of airflow to maintain the 55°C operating rating.
