The Motorola MVME162-014A is a 25 MHz embedded controller based on the MC68LC040 processor. This model combines 4 MB of DRAM with an Ethernet interface and is configured without the VMEbus interface. Its value in a legacy installation depends on matching these exact characteristics to the host equipment and application design.
The MVME162 family uses a 32-bit local bus architecture and includes onboard memory resources for code execution and retained data. Family-level features include flash memory, battery-backed SRAM and a time-of-day clock; the exact capacity and fitted options must be checked against the individual board.
| CPU | MC68LC040 with MMU, 25 MHz |
| DRAM | 4 MB with programmable parity |
| Ethernet | Fitted for this model configuration |
| VMEbus | Interface not fitted |
| SCSI | Not fitted in this configuration |
| Local retained memory | 512 KB battery-backed SRAM in the -014A configuration |
| Board format | MVME162 family, 6U board architecture |
The absence of a VMEbus interface is a decisive selection point. Check how the existing equipment connects to the controller, how Ethernet is wired, and whether the application expects local-bus or VMEbus access. A family-level resemblance is not enough to confirm compatibility.
REQUEST AVAILABILITY ↗Before commissioning, confirm the board revision, supply rails, airflow, installed memory, boot firmware and Ethernet network settings. The serial interface arrangement and transition-module wiring should match the established system. A replacement board may require configuration work even when the part number is correct.
Battery-backed circuitry deserves attention during long-term storage and recommissioning. Preserve required settings, assess battery condition and verify that the application starts normally after power cycling.
These models share a product family, but the processor and interface differences affect system compatibility.
| Model | Memory / CPU | Selection Point |
| MVME162-001 | 1 MB DRAM, MC68LC040 | 512 KB SRAM; lower DRAM capacity |
| MVME162-014A | 4 MB DRAM, MC68LC040 | Ethernet fitted; no VMEbus interface |
| MVME162-020A | 4 MB DRAM, MC68040 | VMEbus interface; no Ethernet or SCSI |
MVME162-014A is the logical candidate when the original system specifically uses the Ethernet-equipped, non-VMEbus configuration. Do not replace it with a VMEbus-equipped board unless the system design supports that change. Also verify the processor variant, memory map and firmware dependencies.

Not when the application depends on the VMEbus interface. MVME162-014A is configured without that interface. Check the host architecture and bus dependencies before selecting it as a replacement.
Ethernet is part of this model's configuration. The network wiring, software support, connector arrangement and communication settings still need to match the installation.
A matching DRAM capacity does not guarantee equivalent hardware. Processor type, Ethernet and SCSI options, VMEbus presence, firmware and application assumptions can differ between variants.
Verify physical connections, network configuration, application drivers, boot settings and board condition. Also confirm that the system's software is designed for the fitted Ethernet hardware.
Provide the complete model designation, board revision, processor marking, memory configuration, system interface requirements, quantity and required delivery date. A clear photo of the nameplate can help confirm the exact variant.
Contact us within 7 days after delivery if an issue occurs. The returned item must be in its original condition, and the return reason must be clearly stated. A return or replacement will be arranged after receipt and assessment. The buyer covers return shipping costs.
