PI7C8150BNDE

Specialized Overview

The PI7C8150BNDE is an asynchronous 2-port PCI-to-PCI bridge manufactured by Diodes Incorporated (formerly Pericom). It operates at a maximum clock frequency of 66 MHz and supports a 32-bit data bus width. The device functions as a PCI bus controller with a 32-bit address bus, powered by a single 3.3 V supply voltage ranging from 3.3 V to 3.6 V. It is available in a 208-pin FQFP package and supports an extended commercial operating temperature range from 0°C to +85°C.

Specialized Feature Summary

• Supports asynchronous bridging between primary and secondary PCI buses
• Provides full compliance with PCI Local Bus Specification for Type 0 and Type 1 configuration cycles
• Includes integrated JTAG boundary scan controller for manufacturing test access

Specialized Applications

• Connecting legacy PCI expansion cards to modern system architectures
• Expanding PCI bus capacity in industrial control systems
• Enabling hot-plug capabilities in server infrastructure

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature rating. Confirm current availability status as component lifecycles may change. Ensure the selected variant matches the required interface voltage and pinout specifications for the target design.

Specialized Selection Notes

Select this component when designing systems requiring connection between two independent PCI domains. Verify that the 3.3 V power supply meets the specified tolerance. Ensure the PCB layout accommodates the 208-pin FQFP footprint or the alternative PBGA option if space constraints require it.

Specialized Part Context

This part belongs to the PI7C8150B family of asynchronous PCI-to-PCI bridges. It serves as a critical interface solution for maintaining backward compatibility with older PCI peripherals while integrating them into newer platform designs. The device replaces discrete logic solutions previously used for bus bridging.

Specialized Replacement Considerations

Check for updated revisions within the PI7C8150B series. Verify pin compatibility if substituting with other 208-pin FQFP bridge controllers. Consult the manufacturer's obsolescence notices for long-term supply assurance.
