TSI382-66CQY

Specialized Overview

The TSI382-66CQY is a high-performance bridge integrated circuit manufactured by Renesas Electronics Corporation, designed to connect single-lane PCI Express interfaces to 32-bit PCI buses. The device supports PCI interface clock frequencies up to 66 MHz and operates within a temperature range of -40°C to +85°C. It utilizes a CABGA-144 package with a pitch of 1 mm and dimensions of 13.0 x 13.0 x 1.4 mm. Power requirements include supply voltages of 1.2 V and 3.3 V. The component features moisture sensitivity level 3 (168 hours) and is classified under ECCN EAR99.

Specialized Feature Summary

• Provides non-transparent bridging support for flexible system design
• Supports transparent, opaque, and non-transparent addressing modes
• Enables connection of up to four PCI devices via dedicated clock and arbitration pins

Specialized Applications

• High-performance computing systems requiring PCIe to PCI interconnectivity
• Industrial automation controllers utilizing legacy PCI peripherals
• Telecommunications infrastructure equipment needing low-latency data transfer

Specialized Procurement Notes

Verify the specific suffix CQY against official Renesas documentation to confirm package type and operating temperature grade. Confirm availability status as distribution channels may list this part as obsolete or limited supply. Ensure compliance with RoHS directives if required for the target market. Check for any product change notices affecting pinout or electrical characteristics before finalizing procurement plans.

Specialized Selection Notes

Select the TSI382-66CQY when a small footprint bridge between PCIe and 32-bit PCI is required. Consider the 144-pin CABGA package for space-constrained designs. Evaluate the need for non-transparent bridging capabilities versus standard transparent modes. Compare performance metrics against similar bridge controllers if higher lane counts are necessary.

Specialized Part Context

This component belongs to the TSI382 series of PCI Express to PCI bridges. It shares functional similarities with the TSI381 but offers optimized form factors. The series is engineered for applications demanding high throughput and low latency between modern PCIe hosts and traditional PCI peripherals.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers for the TSI382-66CQY were not identified in available documentation. Designers should consult Renesas technical support for validated alternatives or consider redesigning for newer interface standards.
