Product Introduction
MOTOROLA MVME215-1 operates as a reliable VMEbus single-board computer. This industrial automation unit handles legacy control and data processing tasks efficiently.
It leverages a 25MHz Motorola 68030 processor with an MC68882 floating-point coprocessor. The board provides up to 4MB of SRAM and supports extended temperature ranges for harsh environments.

Quality Control Process
We validate every MOTOROLA MVME215-1 through comprehensive functional testing. First, we perform a cold boot sequence to verify firmware and VxWorks/pSOS BSP integrity. Next, we run multi-pass memory diagnostics on the SRAM to catch bit errors. We validate the Ethernet and serial interfaces under sustained load. Parallel and 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
❗ FPU Dependency: This SBC includes an MC68882 floating-point coprocessor. Software compiled for hardware FPU will fail if installed on a variant without it.
❗ SRAM Expansion Limits: The board supports up to 16MB SRAM. Exceeding this limit or using incompatible modules causes boot failures.
❗ VMEbus Jumper Settings: Address and arbitration jumpers must match your legacy backplane configuration. Mismatches cause silent bus hangs.
❗ Legacy Serial Cables: RS-232/422/485 ports share connectors but use different pinouts. Incorrect cabling damages the UART transceivers.
Keep these in mind and you’ll cut 90% of rework time.
