89HPES24N3A1ZCBX

Overview

The 89HPES24N3A1ZCBX is a PCI Express interface integrated circuit manufactured by Renesas Electronics. It functions as a 24-lane, 3-port switch supporting PCIe Gen1 specifications. The device provides high-performance I/O expansion and switching capabilities between an upstream port and downstream ports. Key technical attributes include support for root-to-peripheral and peer-to-peer data transfers, internal buffering, and flow control credits optimized for maximum bandwidth and large payloads. The component is designed for low latency and low power consumption applications.

Feature Summary

• Supports non-blocking switching architecture optimized for I/O expansion
• Enables both root-to-peripheral and peer-to-peer data transfer modes
• Integrates internal buffering and flow control mechanisms

Applications

• PCIe I/O expansion systems
• Root-to-peripheral interconnect architectures
• Peer-to-peer downstream switching configurations

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted or unavailable through standard channels. Verification of current stock status and alternative sourcing options should be conducted directly with authorized suppliers or distributors before procurement planning.

Selection Notes

Designers requiring this specific 24-lane, 3-port PCIe Gen1 switch configuration must account for its discontinued status. Selection should prioritize verified legacy inventory or evaluate newer generation switches from the same family that offer compatible pinouts and feature sets while ensuring long-term supply stability.

Part Context

The 89HPES24N3A1ZCBX belongs to the IDT/Renesas 89HPE series of PCIe switches. This series focuses on providing scalable interconnect solutions for computing and storage applications. The part number suffix indicates specific packaging and environmental compliance variations within the broader product line.
