TSI382A-66IL

Specialized Overview

The TSI382A-66IL is a PCI Express to PCI bridge integrated circuit manufactured by Renesas Electronics. It provides a high-performance, small-footprint solution for connecting single-lane PCI Express (PCIe) to 32-bit PCI buses. The device supports PCI interface clock frequencies up to 66 MHz and operates with dual power supplies of 1.2 V and 3.3 V. It is housed in a 144-pin CABGA package and functions within an operating temperature range of -40°C to +85°C.

Specialized Feature Summary

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

Specialized Applications

• Converting PCIe host systems to support legacy 32-bit PCI expansion cards
• Industrial control systems requiring low-latency data transfer between modern processors and older peripheral interfaces
• Embedded computing platforms needing compact form factor bridges for mixed-bus environments

Specialized Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Check for original manufacturer markings and packaging integrity. Confirm RoHS compliance documentation matches current regulatory requirements. Validate part number suffixes against official datasheets to ensure correct speed grade and package type.

Specialized Selection Notes

Select this component when a single-lane PCIe to 32-bit PCI bridge is required. Ensure the design accommodates the specific 1.2 V and 3.3 V power supply rails. Verify that the PCB layout supports the CABGA-144 package dimensions. Consider thermal management for the specified industrial temperature range.

Specialized Part Context

This component belongs to the TSI382 series of bridge controllers. It is functionally similar to the TSI381 but may differ in specific electrical characteristics or pin configurations. Both are designed for PCIe to PCI bridging applications. The TSI382A variant typically denotes a specific speed bin or revision within the family.
