Product Introduction
Designed for installation inside a VMEbus chassis, the Motorola MVME215-1 provides additional battery-backed CMOS RAM storage for embedded systems where configuration retention is required after power removal. The module operates as a VMEbus slave device and supports standard and extended addressing modes, making it suitable for legacy industrial computing architectures that cannot tolerate loss of stored parameters.
This is a memory preservation device rather than a processor board. Treat it accordingly during maintenance. Inspect the battery assembly, VME connector contacts, PCB surface, and mounting hardware before installation. The onboard battery is the critical preservation point (a failed backup cell can erase retained information even when the RAM devices themselves remain functional).

Global Compliance & Industry Certifications
Expected compliance considerations for this class of Motorola VME industrial hardware include:
- CE Mark for applicable EMC requirements when installed within a compliant system enclosure.
- UL/cUL Listed or Recognized status depending on the final equipment assembly.
- ATEX/IECEx consideration only when integrated into a certified hazardous-area system with approved enclosure and protection methods.
- Marine approvals such as DNV GL where used inside certified vessel or offshore automation equipment.
For industrial memory modules installed in regulated environments, the complete chassis certification matters. The module alone does not provide hazardous-area protection or enclosure approval.
Verify specific lot certifications with OEM.
Long-Term Storage & Asset Preservation Guide
- Store the inside its original anti-static (ESD) shielding bag. Protect the VME edge contacts from oxidation and accidental mechanical damage.
- Inspect the onboard battery before deployment. Battery-backed memory modules require special attention because electrolyte leakage or reduced backup capacity can compromise retained data.
- Maintain warehouse humidity below 60% RH to prevent connector corrosion and PCB coating degradation.
Check the date code. For legacy memory hardware, battery condition and traceability records are as important as the module itself.
Physical Installation Prerequisites
- Install only into a compatible VMEbus chassis supporting P1/P2 backplane connections.
- Verify the assigned VME address range before startup.
- Confirm +5 VDC and +12 VDC backplane supply stability.
- Maintain adequate chassis airflow around the module to prevent heat accumulation.
- Ensure chassis grounding and protective earth bonding are complete.
- Use ESD protection when handling the board.
- Confirm retained-memory requirements and application compatibility before removing or replacing an existing module.
Buyer’s FAQ (Logistics & Compliance Focus)
Q: What HS Tariff Code is commonly reviewed for the Motorola ?
A: VME memory modules are commonly evaluated under HS 8471 or related electronic processing equipment classifications, depending on declared function and destination-country customs interpretation.
Q: Does Country of Origin (COO) documentation matter for this legacy memory module?
A: Yes. COO records support customs clearance, supplier qualification, and lifecycle tracking. Maintain original labels, serial information, purchase records, and receiving inspection reports.
Q: Should shipping insurance be purchased for the ?
A: Yes. Although lightweight, this module contains legacy memory components and battery-backed retention circuitry that may be difficult to replace. Use ESD packaging, moisture protection, shock control, and declared-value insurance.
Q: Does the Motorola include the latest firmware pre-loaded?
A: No. The is a CMOS RAM memory expansion module, not a processor controller. It does not contain application firmware. System software compatibility depends on the host VME controller and stored configuration data.
