TSI350A-66CQY

Specialized Overview

The TSI350A-66CQY is a PCI bus bridging component manufactured by Renesas Electronics Corporation. It facilitates data transfer between two PCI buses operating in 32-bit mode at frequencies up to 66 MHz. The device is housed in a 31mm x 31mm Quad Flat Package (QFP). This bridge IC provides the necessary interface logic to connect distinct PCI segments, ensuring signal integrity and protocol compliance for high-speed peripheral interconnects within computer systems.

Specialized Feature Summary

• Supports dual PCI bus operation with frequency scaling up to 66 MHz
• Enables 32-bit data path architecture for enhanced throughput
• Integrates bridging logic for seamless segment interconnection

Specialized Applications

• PCI-to-PCI expansion architectures
• High-performance computing system interconnects
• Industrial control systems requiring multiple PCI segments

Specialized Part Context

The TSI350 series belongs to Renesas' legacy portfolio of peripheral component interconnect solutions. These components were designed to address the growing demand for scalable I/O bandwidth in desktop and server platforms during the era of widespread 66 MHz PCI adoption. The TSI350A variant specifically denotes the commercial temperature grade version of this bridge controller.

Specialized Replacement Considerations

Verify pin compatibility and electrical characteristics against current available bridge controllers. Ensure that the replacement supports the required 66 MHz frequency and 32-bit width. Check for any differences in power management features or interrupt handling mechanisms compared to the original TSI350A specification.
