89HPES24N3A2ZCBX8

Overview

The 89HPES24N3A2ZCBX8 is a PCI interface IC manufactured by Renesas Electronics, functioning as a PCIe switch with 24 lanes and 3 ports. It supports PCIe Gen1 specifications and provides high-performance I/O expansion capabilities. The device architecture facilitates root-to-peripheral and peer-to-peer data transfers, incorporating internal buffering and flow control credits to optimize bandwidth for large payloads. Designed for low latency and power consumption, it serves as an interface solution for system interconnects requiring multiple downstream connections.

Feature Summary

• Supports root-to-peripheral and peer-to-peer switching architectures
• Includes internal buffering and flow control credits for optimized bandwidth
• Provides low latency and low power operation

Applications

• PCIe I/O expansion systems
• System interconnect switching
• Root-to-peripheral data transfer applications

Procurement Notes

Verify the exact suffix 'A2' against official Renesas documentation, as public records primarily list 'A1'. Confirm current lifecycle status, as related variants are marked obsolete. Ensure compatibility with required packaging formats such as Reel or Cut Tape if available through authorized channels.

Selection Notes

Select this component when a 3-port, 24-lane PCIe Gen1 switch is required. Compare against the 89HPES24T3G2 series for Gen2 support needs. Verify package type requirements, typically FCBGA, and ensure thermal management aligns with the low-power design specifications of the PEs24 family.

Part Context

This part belongs to the IDT/Pes24 family of PCIe switches acquired by Renesas. It is functionally similar to the 89HPES24N3A1ZCBX8, differing potentially in manufacturing revision or specific configuration options defined by the suffix. It sits within the broader category of high-performance interface ICs designed for server and storage infrastructure.

Replacement Considerations

Publicly confirmed substitute part numbers for the specific 'A2' suffix variant are not available. Consider the 89HPES24N3A1ZCBX8 for functional equivalence if the suffix difference is non-functional. For Gen2 upgrades, evaluate the 89HPES24T3G2 series.
