Technical Specifications

Solving the Discontinued Hardware Crisis

The MVME162 series was a backbone compute module in VMEbus-based industrial control systems deployed throughout the 1990s and early 2000s. These systems remain operational in sectors where the cost and risk of full platform migration outweigh the inconvenience of sourcing legacy hardware — including power generation, chemical processing, water treatment, and heavy manufacturing.

The MVME162-010A specifically served as the central processing element in multi-slot VMEbus racks, coordinating I/O, real-time task scheduling, and inter-board communication. There is no modern drop-in equivalent that preserves the existing software environment, backplane pinout, and interrupt handling behavior simultaneously. Any replacement with a non-identical module requires firmware porting, system revalidation, and in regulated industries, re-certification — a process that routinely takes 6 to 18 months and carries substantial engineering cost.

How to extend your VMEbus automation asset life by 5 to 10 years — without a full system overhaul:

Condition & Reliability Assurance

DriveKNMS applies a structured 5-step inspection protocol to all obsolete embedded controller modules before they are offered for sale. This process is not a marketing claim — it reflects the practical reality that a module of this age requires active verification, not assumption.

• Step 1 – Visual and mechanical inspection: Full examination of PCB surface, edge connector pins, and component seating. Pin corrosion, bent contacts, and physical damage are documented and assessed for impact on function.
• Step 2 – Electrolytic capacitor assessment: Capacitors on boards of this vintage are a primary failure risk. We inspect for visible bulging, electrolyte leakage, and where test equipment permits, measure ESR on critical filter capacitors in the power regulation circuit.
• Step 3 – Firmware and configuration verification: Where the board can be powered safely, boot behavior is observed and firmware revision is recorded. Boards that fail to complete POST are segregated and not offered as functional units.
• Step 4 – RTC battery and backup circuit check: The MVME162 series uses an onboard battery for real-time clock and NVRAM retention. Battery condition is checked; depleted batteries are flagged in the unit record.
• Step 5 – Connector and interface pin inspection: VMEbus P1/P2 connector pins are inspected under magnification for oxidation, mechanical deformation, and contamination. Boards with compromised connector integrity are not listed as ready-to-install units.

Units that pass all five steps are offered as verified functional or verified pull. Units with identified but non-critical issues are disclosed in full. We do not list boards as functional without completing this process.

Key Features for System Maintenance

• Drop-in replacement: The MVME162-010A installs directly into any standard 6U VMEbus slot. No backplane modification, no chassis rework.
• No reprogramming required when the replacement unit carries the same firmware revision as the unit being replaced. Configuration is held in NVRAM — restore from your documented backup and the system returns to its prior state.
• Avoids engineering reconstruction costs: Replacing this board with a non-identical modern alternative requires porting real-time software, revalidating I/O mapping, and in many cases rewriting interrupt service routines. A like-for-like MVME162-010A replacement eliminates all of that work.
• Preserves existing operator qualification: Your maintenance team already knows this hardware. A board swap does not require retraining or updated maintenance procedures.
• Supports extended asset life planning: With a verified spare on hand, facilities can defer full system migration on their own schedule rather than under emergency conditions.

Q: How do I know the unit is genuine and not a counterfeit?
A: All units are sourced from decommissioned industrial installations or verified distributor overstock — not manufactured reproductions. Motorola board markings, revision labels, and PCB construction are consistent with original production. We do not source from unverified secondary markets.

Q: Can you source specific firmware versions?
A: We record firmware revision on all units that can be powered for inspection. If you require a specific revision, contact us with your requirement before purchase and we will confirm whether a matching unit is available.
