TSI350A-66CQ

Specialized Overview

The TSI350A-66CQ is a PCI-to-PCI bridge interface IC manufactured by Renesas Electronics. It facilitates data bridging between two PCI buses operating at frequencies up to 66 MHz in 32-bit mode. The device supports a maximum clock frequency of 66 MHz and functions within a supply voltage range of 3 V to 3.6 V. It is designed for surface mount installation in a CQFP package, suitable for industrial temperature ranges from 0°C to +85°C. This component serves as a critical link for expanding PCI bus architectures in legacy systems.

Specialized Feature Summary

• Provides bridging functionality between two independent PCI buses
• Supports 32-bit data bus width operation
• Enables PCI bus speeds up to 66 MHz

Specialized Applications

• Industrial control systems requiring PCI expansion
• Legacy computer hardware maintenance and upgrades
• Embedded systems utilizing standard PCI interfaces

Specialized Procurement Notes

Verify the exact suffix designation carefully, as the TSI350A series includes variants with different packages such as CLV (PBGA) and CQ (CQFP). Confirm that the specific CQFP package matches the target PCB footprint. Check current availability status as this component may be discontinued or subject to limited supply constraints depending on the manufacturer's lifecycle stage.

Specialized Selection Notes

Select the TSI350A-66CQ when a 32-bit PCI-to-PCI bridge is required in a CQFP package. Ensure the design accommodates the 3 V to 3.6 V power supply requirements. Verify that the application environment stays within the 0°C to +85°C operating temperature range. Consider alternative packages like PBGA if space constraints differ from the CQFP dimensions.

Specialized Part Context

The TSI350A-66CQ belongs to the TSI350A family of PCI interface controllers. This series is engineered to provide reliable connectivity between PCI segments. The '66' in the model number indicates support for 66 MHz bus speeds, while the 'CQ' suffix specifies the plastic quad flatpack no-lead (or similar) package type used for surface mounting.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Renesas resources for cross-reference information or verify compatibility with generic PCI bridge solutions if direct replacement is necessary.
