89HPES24T6G2ZBALI

Specialized Overview

The 89HPES24T6G2ZBALI is a PCI Express switch interface integrated circuit manufactured by Renesas Electronics Corporation. It provides 24 PCIe Gen2 lanes and supports six switch ports, delivering high-performance system interconnect switching capabilities. The device features a non-blocking architecture optimized for deterministic throughput across multiple traffic flows. It utilizes a 324-FCBGA package with dimensions of 19x19 mm. The component operates on a 3.3V supply voltage and is designed for surface mount installation. This specific part number is identified as obsolete within the manufacturer's product lifecycle.

Specialized Feature Summary

• Supports 24 PCIe Gen2 lanes with six switch ports for high-performance I/O expansion
• Non-blocking switch architecture ensures full line rate throughput regardless of switch loading
• Enables root-to-peripheral and peer-to-peer data transfers between downstream ports
• Includes internal buffering and flow control credits optimized for large payloads

Specialized Applications

• PCIe I/O expansion systems requiring multi-port connectivity
• High-performance system interconnect switching applications
• Peer-to-peer switching architectures in server or storage environments

Specialized Procurement Notes

This component is officially classified as obsolete by the manufacturer. Verification of availability should focus on surplus distributors rather than authorized channels. Confirm RoHS compliance status, as indicated documentation lists it as non-compliant. Ensure the specific suffix matches required lead-free or temperature grade specifications before procurement.

Specialized Selection Notes

Select this model when a 24-lane, 6-port PCIe Gen2 switch is required for legacy system designs. Verify compatibility with the 324-FCBGA footprint during PCB layout. Consider that the obsolete status may impact long-term supply stability. Evaluate alternative newer generation switches if future-proofing is a priority, as this device represents an earlier PCIe Gen2 specification tier.

Specialized Part Context

This part belongs to the 89HPES series of PCI Express switches from Renesas (formerly IDT). It shares architectural similarities with other models like the 89HPES24T3G2 but offers a different port configuration. The series is characterized by low latency and power efficiency for system interconnect applications. Documentation indicates this specific variant was part of a broader family including Gen1 and Gen2 options with varying lane counts.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status, direct pin-compatible replacements are not explicitly listed. Engineers should consult Renesas technical support for current equivalent recommendations or evaluate generic PCIe switches with matching lane and port counts.
