The PI7C9X440SLAFDE is a PCIe to four-port PCI/PCI-X bridge manufactured by Pericom (now Diodes Incorporated). This bridge allows older PCI and PCI-X devices to be used in newer systems that support the PCIe (Peripheral Component Interconnect Express) standard. It is commonly used in industrial PCs, embedded systems, and other applications where legacy PCI devices need to be integrated into modern computing platforms. The PI7C9X440SLAFDE provides a reliable and efficient bridge between the two bus architectures.

Applications

• Industrial PCs: Used in industrial PCs to support legacy PCI and PCI-X cards.
• Embedded Systems: Employed in embedded systems to integrate older PCI devices into newer systems.
• Data Acquisition Systems: Integrated into data acquisition systems to connect PCI-based data acquisition cards.
• Test and Measurement Equipment: Utilized in test and measurement equipment to support PCI-based instruments.

Features

• PCIe to PCI/PCI-X Bridge: Provides a bridge between PCIe and PCI/PCI-X bus architectures.
• Four-Port Support: Supports up to four PCI/PCI-X devices.
• Transparent Bridging: Offers transparent bridging, allowing PCI devices to operate as if they were directly connected to the PCIe bus.
• High Performance: Delivers high-performance data transfer between the PCIe and PCI buses.
• Flexible Configuration: Supports various configuration options to accommodate different system requirements.

Benefits

• Legacy Device Support: Enables the use of legacy PCI and PCI-X devices in modern systems.
• System Integration: Simplifies the integration of PCI devices into PCIe-based systems.
• Increased System Flexibility: Increases system flexibility by supporting a wider range of peripherals.
• Cost Savings: Reduces costs by allowing the reuse of existing PCI devices.
