TSI381-66IL

Specialized Overview

The TSI381-66IL is a PCI interface IC functioning as a bridge from single-lane PCI Express to 32-bit PCI. It supports a maximum PCI clock frequency of 66 MHz and operates on 1.2 V and 3.3 V power supplies. The device utilizes a CABGA-144 package with dimensions of 13.0 x 13.0 x 1.4 mm and a 1 mm pitch. It functions within an operating temperature range of -40°C to +85°C and is classified as moisture sensitive level 3.

Specialized Feature Summary

• Provides high-performance bridging between single-lane PCI Express and 32-bit PCI interfaces.
• Supports transparent, opaque, and non-transparent addressing modes for design flexibility.
• Operates without power sequencing restrictions.

Specialized Applications

• PCIe to PCI bridge implementations
• Industrial systems requiring extended temperature ranges
• Prototyping and evaluation using compatible development kits

Specialized Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verify RoHS compliance status and lead times carefully, as standard supply chains no longer support this part number. Confirm package integrity due to potential age-related handling risks.

Specialized Selection Notes

Select this component only if legacy PCI slot integration with PCIe hosts is required. Ensure the design accommodates the specific 144-pin CABGA footprint. Consider that the part is discontinued; verify long-term availability requirements against current inventory levels before finalizing the bill of materials.

Specialized Part Context

The TSI381 series includes variants such as the TSI381-66ILV and the TSI381-RDK1 evaluation board. The IL suffix denotes the industrial temperature grade and leaded construction. This specific model serves as the hardware bridge enabling communication between modern PCIe buses and older 32-bit PCI peripherals.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is obsolete, alternative solutions require manual verification of pin compatibility and electrical specifications with other manufacturers offering similar PCIe-to-PCI bridge functionality.
