Emerson / Motorola MCP750 CompactPCI Single Board Computer (400 MHz)

The Emerson/Motorola MCP750 is a single-slot CompactPCI single board computer built on the PowerPC 750 32-bit microprocessor architecture. Operating at 400 MHz, it delivers the processing power and I/O integration required for embedded industrial control, communications, and systems. The board combines a 1MB base flash footprint with configurable DRAM up to 256MB, dual Ethernet ports, four serial channels, USB connectivity, and CompactFlash support - all within a standard CompactPCI form factor.
