89HPES24T3G2ZCBLI8

Overview

The 89HPES24T3G2ZCBLI8 is a PCI Express interface integrated circuit manufactured by Renesas Electronics Corporation. It functions as a PCIe Gen2 switch providing 24 lanes across three ports, optimized for I/O expansion. The device supports root-to-peripheral and peer-to-peer data transfers with internal buffering and flow control credits to maximize bandwidth and handle large payloads. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 676-pin FCBGA package measuring 27x27 mm with a 1 mm pitch. The component requires 3.3V supply voltage and is classified as obsolete.

Feature Summary

• Provides high-performance I/O expansion and switching between one upstream port and two downstream ports or peer-to-peer switching between downstream ports.
• Features a non-blocking architecture optimized for maximum bandwidth and large payload support through internal buffering and flow control credits.
• Supports low latency and low power operation suitable for demanding system interconnect applications.

Applications

• PCIe Gen2 system interconnect switching
• High-performance I/O expansion systems
• Root-to-peripheral data transfer architectures

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on distributor surplus stocks or secondary market sources rather than direct manufacturing orders. Confirm RoHS compliance status and moisture sensitivity level (MSL 4) prior to procurement, as these specifications may vary based on production lot dates. Ensure compatibility with existing PCB footprints given the specific 676-FCBGA package dimensions.

Selection Notes

Select this part when designing systems requiring three-port PCIe Gen2 switching capabilities with a 27x27 mm form factor. Verify that the design accommodates the 1 mm pitch BGA package and supports the required 3.3V power domain. Consider the industrial temperature grade if operating in environments outside standard commercial ranges. Evaluate alternative newer generation switches if long-term supply assurance is critical for the product lifecycle.

Part Context

The 89HPES24T3G2ZCBLI8 belongs to the 89HPES series of PCIe switches from Renesas (formerly IDT). This series focuses on providing deterministic switching performance for server and storage applications. The 'ZCBLI8' suffix indicates specific packaging, temperature grade, and lead-free status variations within the broader 89HPES24T3G2 family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must evaluate newer PCIe Gen3/Gen4 switch families from Renesas or other vendors, ensuring pinout and electrical compatibility during migration.
