Emerson / Motorola MVME162-510A Embedded Controller

The Emerson / Motorola MVME162-510A is a VMEbus-based embedded controller designed for industrial, telecommunications, transportation, and defense applications requiring real-time control, data acquisition, and computational performance. Built around the Motorola 68040 microprocessor family, this single-board computer delivers processing power in a compact form factor with extensive memory options, multiple communication interfaces, and DMA capabilities for high-speed data transfers.

## Technical Specifications

**Processor Options**
• 32 MHz MC68040 with 8KB cache, MMU, and FPU
• 25 MHz MC68040 with 8KB cache, MMU, and FPU
