89HPES24N3A1ZCBXGI

Overview

The Renesas Electronics Corporation 89HPES24N3A1ZCBXGI is a PCI Express interface integrated circuit designed for high-performance I/O expansion. It functions as a PCIe switch providing 24 lanes and three ports, supporting Gen1 operation at 2.5 GT/s. 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. It operates on a 3.3V supply voltage and is housed in a surface-mount FCBGA package containing 324 pins with dimensions of 19x19 mm.

Feature Summary

• Provides high-performance switching between upstream and downstream ports or peer-to-peer connections
• Supports automatic link width negotiation to adapt to different connected devices
• Features low latency architecture with optimized internal buffering for large payloads

Applications

• PCIe I/O expansion systems
• Server infrastructure
• Storage subsystems

Procurement Notes

Verify the exact suffix ZCBXGI against official Renesas documentation to confirm temperature grade and lead-free status. Confirm current availability as this component may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and power delivery requirements before procurement.

Selection Notes

Select this model when a three-port PCIe Gen1 switch solution is required for system interconnect. Compare against other HPES24 variants if higher generation speeds like Gen2 are needed. Verify that the 324-pin FCBGA package fits the design constraints and thermal management capabilities of the target application.

Part Context

This part belongs to the IDT/Renesas 89HPES24 family of PCIe switches. It shares architectural similarities with models like the 89HPES24NT3ZBBX but differs in port count and specific feature sets such as non-transparent bridging support found in six-port variants.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific variant are not available in the provided source material. Consult Renesas technical resources for potential pin-compatible alternatives or updated series replacements.
