Engineering Advantages
- Direct VMEbus Compatibility: Plug-and-play integration with all MVME-series CPU boards supporting VMEbus memory expansion slots.
- High Reliability DRAM: Industrial-grade DRAM ICs rated for extended temperature and vibration environments.
- Zero Firmware Modification: Recognized natively by MVME CPU boards without BIOS or firmware changes.
- Legacy System Longevity: Extends operational life of VMEbus systems without costly platform migration.
- ESD-Protected Design: Full electrostatic discharge protection on all signal lines per VMEbus specification.
System Architecture & Signal Flow
The MVME215-3 interfaces directly to the VMEbus P1/P2 connector rows, presenting its DRAM address space to the VMEbus master (CPU board) via the standard A32/D32 address and data lines. Memory arbitration is handled by the VMEbus system controller on the host CPU board. The module operates as a VMEbus slave device, responding to memory read/write cycles initiated by the master CPU. No additional configuration jumpers are required for standard 4MB address mapping; optional address offset jumpers allow conflict-free co-installation with other memory modules in multi-slot VME chassis.

Technical FAQ
Q: Is the MVME215-3 compatible with MVME162 and MVME167 CPU boards?
A: Yes. The MVME215-3 is compatible with all MVME-series CPU boards that support VMEbus memory expansion via the P1/P2 connector, including MVME162, MVME167, MVME172, and MVME177.
Q: Can multiple MVME215-3 modules be installed in the same chassis?
A: Yes, provided the VME chassis has sufficient slots and the address maps are configured to avoid overlap using the onboard address offset jumpers.
Q: What is the difference between MVME215-1, MVME215-2, and MVME215-3?
A: The suffix denotes memory capacity variants: -1 = 1MB, -2 = 2MB, -3 = 4MB DRAM. The MVME215-3 is the highest-capacity variant in the MVME215 series.
Q: Do you provide a test report with the unit?
A: Yes. A functional test report is available upon request at no additional charge.
Q: What is the lead time for the MVME215-3?
A: In-stock units ship within 2–3 business days. For out-of-stock inquiries, typical sourcing lead time is 5–15 business days.
