## Key Features

• On-chip L2 cache, DMA, and integrated Ethernet controllers
• Dual DDR2 memory controllers for high-bandwidth applications
• Multiple PCI Express pathways enabling flexible mezzanine configurations
• RTM direct-connect support for rear-panel I/O expansion
• Multi-OS support for RTOS and Linux deployments

## Typical Applications

Real-time industrial control, embedded signal processing, VMEbus system upgrades, aerospace and defense computing platforms, and distributed I/O systems requiring high-performance processing with legacy VMEbus compatibility.

## Compatibility & Integration

Fully backward-compatible with existing VMEbus infrastructure. Supports industry-standard PMC-X expansion modules and integrates with Artesyn XMCspan expansion carriers. Direct RTM connection eliminates the need for custom transition solutions.
