The PCI6140-AA33PC is a PCI-to-PCI bridge chip manufactured by Broadcom. It serves as an interface enabling communication between two PCI buses. PCI bridges are essential for expanding the capabilities of computer systems by allowing more devices to be connected than a single PCI bus would allow.

Applications:

• Motherboard designs.
• Expansion card designs.
• Industrial computers.
• Embedded systems requiring multiple PCI buses.
• Server systems.

Features:

• PCI-to-PCI bridge.
• 33 MHz PCI bus speed.
• Supports multiple PCI devices.
• Transparent bridging.
• Configuration register access.
• Interrupt management.

Benefits:

• Enables the connection of more PCI devices than a single bus allows.
• Provides standard PCI bus speed compatibility.
• Facilitates seamless communication between devices on different PCI buses.
• Simplifies system configuration.
• Allows for efficient interrupt handling.

The PCI6140-AA33PC operates at a PCI bus speed of 33 MHz, which is a common standard for PCI devices. The transparent bridging feature means that devices connected to either side of the bridge can communicate with each other as if they were on the same bus. Configuration register access allows the system to configure and manage the bridge, and interrupt management ensures proper interrupt handling between devices on different buses. Broadcom's PCI bridge chips are designed for reliability and performance in demanding computing environments.
