Engineering Advantages
- Deterministic Real-Time Performance — 68040 processor with hardware FPU delivers consistent sub-millisecond interrupt latency for time-critical control loops.
- Full VMEbus Compliance — IEEE 1014-1987 conformant; interoperable with all standard VMEbus I/O, memory, and communication modules across vendors.
- Integrated Multi-Protocol I/O — Onboard Ethernet, SCSI-2, and 4-channel serial eliminate the need for additional interface cards, reducing slot count and system complexity.
- Battery-Backed SRAM — Retains critical process parameters, calibration data, and program state through power interruptions without external UPS dependency.
- Broad RTOS Ecosystem — Validated with VxWorks, OS-9, and LynxOS; existing application software ports without hardware modification.
- Extended Temperature Tolerance — Rated to +55°C continuous operation; suitable for non-air-conditioned industrial enclosures and panel environments.
System Architecture & Signal Flow
The MVME 162-262 occupies a single 6U VMEbus slot and functions as the System Controller (Slot 1) or as a secondary processor node in multi-CPU VMEbus configurations. The onboard 68040 CPU arbitrates the VMEbus via the integrated VMEchip2 ASIC, which manages bus arbitration, interrupt routing, and address decoding across A32/A24/A16 address spaces.
Data flows from field I/O modules (analog, digital, serial) through the VMEbus backplane to the CPU’s local bus, where the RTOS scheduler dispatches control tasks. Ethernet and SCSI interfaces connect directly to the CPU local bus via dedicated DMA controllers, ensuring I/O operations do not stall the control scan cycle. Battery-backed SRAM provides a persistent data store accessible at full CPU bus speed.
Sourcing & Quality Verification
All MVME 162-262 units offered by Konmask are sourced through our verified industrial surplus network and subject to the following quality gates before listing:
- Visual inspection: PCB, connectors, component integrity, and label legibility
- Functional power-on test where applicable
- Firmware revision identification and documentation
- Anti-static packaging with humidity indicator cards
- Photographic documentation of actual unit shipped
Konmask does not list units that fail inspection. Condition grade (Refurbished / Tested Surplus / New Surplus) is stated explicitly on each listing.

Technical FAQ
- Q: Is the MVME 162-262 compatible with my existing MVME 162-2xx series backplane?
- A: Yes. The -262 variant is pin-compatible with all standard 6U VMEbus backplanes used across the MVME 162 family. Verify firmware revision compatibility with your RTOS image before installation.
- Q: What is the difference between MVME 162-262 and MVME 162-263?
- A: The -263 variant typically includes additional DRAM or Flash capacity. Consult the Motorola MVME162 Programmer’s Reference Manual (M68040) for variant-specific memory maps.
- Q: Can this module run VxWorks 6.x?
- A: The MVME 162-262 is validated with VxWorks 5.x BSPs. VxWorks 6.x support depends on Wind River BSP availability for the 68040 target; consult Wind River’s legacy BSP archive.
- Q: Do you provide a warranty?
- A: Konmask offers a 90-day functional warranty on all tested surplus units. Extended warranty and exchange programs are available — contact us for details.
- Q: Can you supply the original Allen-Bradley / Motorola documentation?
- A: We can provide links to publicly available OEM documentation. Proprietary manuals are subject to OEM copyright; Konmask does not redistribute restricted documents.
