## Key Features

• Direct Memory Access (DMA) engine handles single transactions up to 64 MB without processor intervention
• Hardware-based flow control prevents data loss at receiver with fixed-frame data insertion
• Integrated interrupt controller reports link failure, transaction completion, and buffer status
• Byte/word swapping on DMA and register paths provides system flexibility
• Multi-level error detection and status reporting
• Support for front and rear I/O configurations
• Point-to-point topology support

## Typical Applications

• Real-time radar and sonar signal processing
• Medical imaging systems with high-speed data streaming
• Video production and acquisition pipelines
• Sensor array processing requiring low-latency DSP interconnect
• High-throughput telemetry and data logging

## Compatibility & Integration

The SL240 integrates into existing PCI and CompactPCI-based systems via PCIe or XMC form factors. Its specialized sFPDP protocol optimization eliminates traditional overhead associated with general-purpose network stacks, delivering deterministic, low-latency performance essential for time-critical applications.
