The MVME162-212 is a specific 200-series MVME162 configuration rather than a generic MVME162 CPU board. Available technical references consistently identify the model with a 25 MHz MC68LC040, 4 MB DRAM, two IndustryPack ports, and Ethernet.
There is an important distinction within the MVME162 family: the MC68LC040 does not include the floating-point unit found in the MC68040. That matters if the existing application software relies on hardware floating-point operations.
Product Introduction
The Motorola MVME162-212 is a legacy VMEbus embedded controller designed for industrial and OEM computer systems requiring local processing with IndustryPack expansion and Ethernet connectivity. Its 25 MHz MC68LC040 processor is paired with 4 MB of DRAM, 512 KB SRAM, 1 MB Flash memory, two IndustryPack interfaces, and an Ethernet interface with 32-bit local-bus DMA.
For maintenance purposes, the two-IP configuration is particularly important. Many MVME162 variants have four IndustryPack ports or different combinations of SCSI and Ethernet. A replacement must therefore be matched against the actual I/O architecture, application software, memory configuration, and VME system rather than selected only by the MVME162 family name.

Application Scenarios & Field Pitfalls
Engineering Pain Point
The main replacement risk is selecting a newer or superficially similar that has the wrong processor, memory, IndustryPack configuration, or peripheral interfaces. The MVME162-212 is specifically a 2-IP/Ethernet configuration.
Typical Applications
- Industrial machine control — embedded processing with IndustryPack I/O.
- Legacy process-control computers — VME-based control nodes communicating through Ethernet.
- Test and measurement equipment — IndustryPack modules provide application-specific acquisition and control.
- OEM automation systems — proprietary control software running on a dedicated VME controller.
Technical Pitfalls to Avoid
- Do not substitute an MC68040 automatically. The -212 uses the MC68LC040, which lacks the MC68040’s floating-point unit.
- Verify the two IndustryPack ports. The -212 has two IP interfaces, while other configurations use four.
- Check SCSI requirements. The -212 is identified as the Ethernet configuration without SCSI; -213, for example, combines SCSI and Ethernet.
- Preserve the software environment. Boot ROM contents, VME address assignments, IndustryPack drivers, and application firmware can be as important as the physical CPU board.
- Check the exact board markings. One documented -212 has base-board part number 01-W3866B-42A and daughtercard 01-W3913B-02A. These markings are useful for confirming an incoming spare.
Related Products
- — 25 MHz MC68LC040 with 4 MB DRAM but without SCSI or Ethernet; lower-interface configuration.
- — 4 MB configuration with two IndustryPack ports and SCSI instead of Ethernet.
- — 4 MB, two IndustryPack ports, SCSI, and Ethernet; closest feature-rich relative to the -212.
- — 25 MHz MC68040/related 4 MB configuration; processor and interface details differ, so it is not an automatic substitute.
- — 25 MHz 4 MB model with two IndustryPack ports and Ethernet; important comparison when looking for a similar I/O arrangement.
- — 25 MHz MC68040, 4 MB, four IndustryPack ports, and Ethernet; more IP capacity than the -212.
- — 25 MHz MC68040 with 4 MB, four IndustryPack ports, SCSI, and Ethernet.
- — later configuration with 25 MHz , 4 MB memory, and Ethernet; different architecture/configuration from the -212.
- — later 32 MHz configuration with 4 MB memory and four DMA IndustryPack interfaces; useful for migration comparisons but not a drop-in replacement.
Procurement Check
For MVME162-212, specify the complete configuration:
ola — 25 MH40 — 4 MB DRAM — 512 KB SRAM — 1 MB Flash — 2 IndustryPack ports — Ethernet.
The strongest field references identify 01-W3866B-42A as a corresponding board part number and 01-W3913B-02A as the daughtercard marking.
The most important checks before accepting a replacement are vs. , 2-IP vs. 4-IP configuration, Ethernet vs. SCSI, memory size, boot firmware, and the existing VME application environment. A generic “” listing is not sufficient for procurement.
