CA91L8200B-100CE

Specialized Overview

The CA91L8200B-100CE is a multi-port PCI bus switch from the PowerSpan II series, manufactured by Renesas Electronics Corporation. It functions as a bridge between PCI and PowerQUICC II (MPC8260), MPC7xx, PowerPC 7xx, and PMC-Sierra WinPath processors. The device supports processor bus frequencies ranging from 25 MHz to 100 MHz and handles 64-bit/66 MHz or 32-bit/66 MHz PCI 2.2 buses. Key specifications include an integrated non-transparent PCI-to-PCI bridge, four independent bi-directional DMA channels, and PCI bus arbiters on each interface.

Specialized Feature Summary

• Integrates a non-transparent PCI-to-PCI bridge to reduce component count and increase system performance
• Provides four independent bi-directional DMA channels for efficient data transfer
• Includes PCI bus arbiters on each PCI interface for robust bus management

Specialized Applications

• Bridging PCI interfaces to PowerQUICC II (MPC8260) processors
• Connecting PCI buses to MPC7xx and PowerPC 7xx processors
• Interfacing with PMC-Sierra WinPath processors in embedded systems

Specialized Procurement Notes

Verify current availability status as this component may be subject to end-of-life notices. Confirm RoHS compliance requirements against specific project standards. Ensure compatibility with target processor architectures before procurement. Check for any pending product change notifications that might affect long-term supply stability.

Specialized Selection Notes

Select this component when designing systems requiring a bridge between PowerQUICC or PowerPC processors and PCI 2.2 buses. Consider its support for 64-bit/66 MHz and 32-bit/66 MHz configurations. Evaluate the need for integrated non-transparent bridging and multiple DMA channels to simplify board design.

Specialized Part Context

The CA91L8200B belongs to the PowerSpan II family of PCI interface ICs. This series is designed to facilitate connections between various embedded processors and PCI peripherals. The dual configuration allows for enhanced connectivity compared to single-port solutions, supporting complex system architectures.
