Product Introduction
MOTOROLA MVME162-213 operates as a highly reliable VMEbus single-board computer. This industrial automation unit is engineered for mission-critical control and real-time data processing.
It leverages a 25MHz Motorola 68040 processor featuring an integrated FPU and MMU. The board includes 4MB of DRAM, 512KB battery-backed SRAM, and optional SCSI and Ethernet interfaces for robust legacy system integration.

Quality Control Process
We validate every MOTOROLA MVME162-213 through comprehensive functional testing. First, we perform a cold boot sequence to verify the board monitor and VxWorks BSP integrity. Next, we run multi-pass memory diagnostics on the DRAM and SRAM to catch bit errors. We validate the SCSI and Ethernet interfaces under sustained load. Serial ports undergo loopback signal injection testing. Finally, we verify VMEbus arbitration timing using a protocol analyzer. Each replacement module ships in anti-static packaging.
Replacement Pitfall Guide
❗ Battery-Backed SRAM: The 512KB SRAM relies on a backup battery. Check the battery voltage before installation to prevent data loss or boot failures.
❗ SCSI Termination: If utilizing the optional SCSI interface, ensure proper termination. Missing terminators cause intermittent storage failures and bus hangs.
❗ IndustryPack Seating: The four IndustryPack ports use high-density connectors. Misalignment during installation bends pins permanently. Seat modules slowly and evenly.
❗ VMEbus Jumper Settings: Address and arbitration jumpers must match your legacy backplane configuration. Mismatches cause silent bus hangs.
Keep these in mind and you’ll cut 90% of rework time.
