TSI382-66IL

Specialized Overview

The TSI382-66IL is a PCI Express to PCI bridge IC manufactured by Renesas Electronics. It provides a high-performance, small-footprint solution for converting single-lane PCI Express signals to a 32-bit PCI interface. The device supports PCI 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 dimensions of 10x10mm. Power requirements include dual voltage supplies of 1.2V and 3.3V. The component is classified as discontinued and is no longer in active production.

Specialized Feature Summary

• Supports transparent, opaque, and non-transparent bridging addressing modes for design flexibility
• Provides superior performance with low latency between PCI Express and PCI domains
• Includes dedicated clock and arbitration pins to support up to four PCI devices

Specialized Applications

• PCI Express to PCI forward bridging in embedded systems
• Industrial control applications requiring non-transparent bridging support
• Legacy PCI expansion integration into modern PCIe architectures

Specialized Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted to remaining stock from authorized distributors or secondary market sources. Buyers must verify part authenticity and condition carefully due to the discontinuation status. No new units are produced by Renesas Electronics.

Specialized Selection Notes

Engineers should evaluate the TSI382-66IL primarily for maintenance of existing designs rather than new development. The 10x10mm CABGA-144 package requires specific PCB layout considerations. Designers must ensure compatibility with the required 1.2V and 3.3V power rails and confirm that the 66 MHz PCI bus speed meets system timing requirements.

Specialized Part Context

The TSI382 belongs to the TSI382 series of interface ICs designed for bridging PCI Express and PCI technologies. It is functionally similar to the TSI381 but may differ in specific pinout or feature sets. This family addresses the need for backward compatibility in systems transitioning from legacy PCI buses to modern PCIe standards.

Specialized Replacement Considerations

No direct public substitute part numbers are confirmed for this discontinued component. Engineers should consult Renesas technical resources for potential migration paths or alternative bridge solutions that meet the same electrical and form-factor specifications.
