TSI384-133ILV

Specialized Overview

The TSI384-133ILV is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed to bridge PCI Express and PCI-X architectures. It provides a high-performance connection from a four-lane PCI Express (x4) interface to a PCI-X bus operating at frequencies up to 133 MHz. The device supports three distinct addressing modes: transparent, opaque, and non-transparent, offering system designers significant flexibility in memory mapping and configuration. Operating with a single 1.2V supply voltage, the component utilizes a 256-pin Plastic Ball Grid Array (PBGA) package measuring 17x17 mm. It is rated for an industrial temperature range of -40°C to +85°C and complies with RoHS3 standards.

Specialized Feature Summary

• Supports forward bridging between x4 PCI Express and PCI-X interfaces at 133 MHz
• Enables flexible system design through transparent, opaque, and non-transparent addressing modes
• Delivers superior performance characteristics with low latency data transfer capabilities

Specialized Applications

• PCI Express to PCI-X forward bridge implementations
• Non-transparent bridging support in complex system architectures
• High-performance interface solutions requiring small footprint integration

Specialized Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is restricted to existing stock or last-time buy scenarios, with no new production scheduled. Verification of authenticity is critical due to the end-of-life status. Buyers should confirm the specific suffix ILV indicates lead-free composition and verify the package type matches the required 256-PBGA form factor before acquisition.

Specialized Selection Notes

Engineers selecting this part must account for its discontinued status and limited lifecycle availability. The device requires a 1.2V power supply and operates within a standard industrial temperature range. Designers should ensure their PCB layout accommodates the 17x17mm PBGA package and that the system architecture leverages the supported non-transparent bridging features effectively.

Specialized Part Context

The TSI384 belongs to the Tsi384 series of interface ICs produced by Renesas Electronics. This series focuses on providing robust connectivity between modern PCIe standards and legacy PCI-X buses. The TSI384-133ILV specifically denotes the lead-free variant of the standard TSI384-133IL model, maintaining identical electrical and functional specifications while adhering to environmental compliance requirements.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may require careful evaluation of electrical compatibility and firmware adjustments.
