89HPES24N3A1ZCBX8

Overview

The Renesas Electronics Corporation 89HPES24N3A1ZCBX8 is a PCI Express interface integrated circuit designed for high-performance I/O expansion. It functions as a PCIe switch featuring 24 lanes and 3 ports, supporting PCIe Gen1 specifications. The device facilitates root-to-peripheral and peer-to-peer data transfers with internal buffering and flow control credits optimized for maximum bandwidth and large payloads. Manufactured by Renesas Electronics, this component is classified under PCI Interface ICs within the Interface ICs subcategory. It utilizes an FC-BGA package type and is identified by the alias IDT89HPES24N3A1ZCBX8.

Feature Summary

• Provides high-performance I/O expansion and switching functions between a PCIe upstream port and downstream ports.
• Supports peer-to-peer switching capabilities between downstream ports for flexible system architectures.
• Features internal buffering and flow control credits optimized for maximum bandwidth and large payload sizes.

Applications

• PCIe I/O expansion systems requiring multiple downstream connections.
• Root-to-peripheral data transfer architectures in server or storage environments.
• Peer-to-peer switching applications between peripheral devices.

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted, and Mouser does not currently sell this product in all regions. Verification of current stock status and alternative sourcing channels is required before procurement planning. Historical packaging quantities included reels and cut tape formats.

Selection Notes

Engineers should verify compatibility with PCIe Gen1 specifications, as this device does not support higher generation speeds. The part requires consideration of the specific FC-BGA package constraints and moisture sensitivity levels associated with surface-mount assembly. Designers must account for the EOL status when defining long-term supply chain strategies and lifecycle management plans.

Part Context

The 89HPES24N3A1ZCBX8 belongs to the 89HPES24 series of PCI Express switches from Renesas Electronics (formerly IDT). This series focuses on providing deterministic system interconnect switching with low latency and low power consumption. The specific suffix indicates commercial temperature grade and lead-free composition variations within the broader family of 24-lane, 3-port switch solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct pin-compatible replacements may be limited. Engineers should consult official Renesas resources for potential next-generation upgrades or legacy support options.
