For decades, these boards were the workhorses in embedded systems across defense, aerospace, industrial automation, and telecommunications. If you are maintaining a long-lifecycle system—think flight simulators, radar systems, or specialized industrial controllers—you know this board. It integrates the CPU, memory, and basic I/O (Ethernet, serial) onto a single VME card. The “652SE” suffix indicates a specific build variant with defined memory and feature set. These boards are long out of production by Motorola (later Emerson), making them increasingly difficult to source. The units we have are new old stock (NOS), meaning they are unused and still in their original protective packaging. Each board undergoes a basic power-on and functional verification before shipping to ensure it isn’t a DOA.   Frequently Asked Questions (FAQ) Q: What operating systems will run on this board? A: Historically, the VME172 was a target for real-time operating systems like VxWorks (most common), pSOS, and OS-9. It can also run a bare-metal executive. You will need the specific board support package (BSP) for your OS, which typically includes drivers for the on-board devices (Ethernet, serial, VME interface). If you are replacing a board in an existing system, you must ensure the new board has the same memory map and firmware version, or your OS may not boot. Honestly, getting the exact firmware revision match is the most critical part of a swap. Q: Can I use this board in a standard VME64 chassis? A: Yes. The VME172PA-652SE is a 6U VME board and is compatible with standard VME64 backplanes. It supports A32/D32 addressing and can act as both a VME master and a slave. It will work in older VME chassis as well as newer ones, provided the power supply can handle the load. Q: I’m replacing a VME172 board. How do I ensure the firmware matches? A: Excellent question. The firmware (also called the “boot monitor” or “PROM”) is critical. When the board powers up, it runs this firmware to initialize the hardware and boot the OS. The OS kernel often relies on specific addresses and functions provided by this firmware. If your new board has a different firmware version, the OS may crash on startup. The only way to be sure is to read the firmware version label on the old board’s PROMs, or boot the old board and type a command at the monitor prompt (usually version). We can often provide boards with the firmware revision you specify if we have it in stock. Q: Does this board have a battery for the clock and maybe SRAM? A: Yes. There is a lithium battery on the board that maintains the real-time clock and can also preserve the contents of any battery-backed SRAM. These batteries are old and likely near the end of their life on new old stock boards. We recommend checking the voltage or proactively replacing the battery before relying on it to keep time or data. A dead battery won’t stop the board from running, but you’ll lose the time/date at power-down. Q: Is this board RoHS compliant? A: Probably not. This board was manufactured long before RoHS (Restriction of Hazardous Substances) came into full effect in 2006. It contains lead solder and other materials that are now restricted. This is generally not an issue for industrial and military applications which often have exemptions or are not required to comply with RoHS. If you are shipping equipment into a region with strict RoHS enforcement, you need to verify your exemption status.
