89HPES3T3ZABC

Overview

The 89HPES3T3ZABC is a PCI Express switch interface IC manufactured by Renesas Electronics. It provides high-performance I/O expansion and switching functions between a PCIe upstream port and two downstream ports, or supports peer-to-peer switching between downstream ports. The device features three PCIe Gen1 lanes and three switch ports. It is designed to support root-to-peripheral (upstream-to-downstream) and peer-to-peer (downstream-to-downstream) data transfers. The component utilizes internal buffering and flow control credits optimized for maximum bandwidth and large payloads, ensuring low latency and low power consumption.

Feature Summary

• Supports root-to-peripheral and peer-to-peer data transfer architectures
• Optimized internal buffering and flow control for large payloads
• Designed for low latency and low power operation

Applications

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

Procurement Notes

Verify the current lifecycle status of the 89HPES3T3ZABC before procurement planning. Official documentation indicates this product line may be discontinued or subject to limited supply conditions. Confirm availability through authorized Renesas distributors or direct manufacturer channels. Ensure compliance with RoHS directives and check for specific environmental certifications required for your application. Request official EOL notifications if applicable.

Selection Notes

Select the 89HPES3T3ZABC when a compact solution for three PCIe Gen1 lanes is required. This part is suitable for applications needing one upstream and two downstream ports without complex multi-root partitioning. Consider the 324-CABGA package constraints during PCB layout. Evaluate thermal requirements due to surface mount installation. Compare against newer generation switches if higher bandwidth or additional ports are needed in future designs.
