TSI382-66ILV

Specialized Overview

The TSI382-66ILV 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 13.0 x 13.0 mm and a height of 1.4 mm. Power requirements include 1.2 V and 3.3 V supplies. The component is classified as discontinued.

Specialized Feature Summary

• Supports transparent, opaque, and non-transparent addressing modes for design flexibility
• Includes dedicated clock and arbitration pins for connecting up to four PCI devices
• Features a compact form factor suitable for space-constrained applications

Specialized Applications

• PCI Express to PCI bridging in industrial systems
• Legacy PCI expansion in modern embedded platforms
• Non-transparent bridging support for system isolation

Specialized Procurement Notes

This component is officially discontinued by the manufacturer. Availability is limited to existing stock or secondary market sources. Verify RoHS compliance status carefully, as datasheets may indicate conflicting information regarding lead-free specifications. Confirm package authenticity and moisture sensitivity handling procedures before integration into production workflows.

Specialized Selection Notes

Select this part only when a single-lane PCIe to 32-bit PCI bridge is required with specific non-transparent bridging capabilities. Ensure the design accommodates the 1.2 V and 3.3 V power domains. Consider the physical constraints of the CABGA-144 package during PCB layout. Evaluate alternative components if current supply chain stability is critical for long-term production.

Specialized Part Context

The TSI382 belongs to the TSI382 series of interface ICs designed for bridging PCI Express and PCI architectures. It serves as a successor to earlier bridge solutions, offering improved performance and smaller footprint options compared to previous generations. The device is part of Renesas' portfolio of specialized interface controllers aimed at maintaining compatibility between evolving PCIe standards and legacy PCI peripherals.
