The PI7C8150ND is a PCI Express to PCI bridge, designed to provide a seamless connection between PCI Express and legacy PCI bus architectures. Manufactured by Pericom (now Diodes Incorporated), this bridge enables systems with PCI Express chipsets to interface with existing PCI peripherals and expansion cards. It's a crucial component for maintaining compatibility and extending the lifespan of older PCI-based hardware in newer systems.

Applications:

• Connecting legacy PCI cards to modern PCI Express based motherboards.
• Industrial PCs requiring both PCI Express and PCI slots.
• Embedded systems needing PCI connectivity through a PCI Express interface.
• Data acquisition systems using PCI data acquisition cards in a PCI Express environment.
• Test and measurement equipment needing to interface with PCI instruments.

Features:

• Compliant with PCI Express Base Specification Revision 1.0a.
• Compliant with PCI Local Bus Specification Revision 2.3.
• Supports both Master and Target PCI operations.
• Integrated PCI clock request function.
• Supports up to 133 MHz PCI clock frequency.
• Supports PCI Express Advanced Error Reporting (AER).
• Supports up to 256 bytes of PCI Express Maximum Payload Size.
• Integrated DMA controller for efficient data transfer between PCI Express and PCI buses.
• Configuration via PCI Express interface.
• Lead-free and RoHS compliant.

Benefits:

• Extends the life of legacy PCI peripherals by allowing them to be used in newer systems with PCI Express.
• Provides a cost-effective solution for maintaining compatibility between different bus architectures.
• Simplifies system design by handling the complexities of PCI Express to PCI bridging.
• Ensures reliable data transfer with integrated DMA controller and error reporting.
• Offers flexibility in system configuration through PCI Express interface.
• Reduces development time and cost by providing a complete bridging solution.
