89HPES24N3A1ZCBXG

Overview

The Renesas Electronics 89HPES24N3A1ZCBXG is a PCI Express I/O expansion switch featuring 24 lanes and 3 ports. It supports PCIe Gen1 specifications with a maximum clock frequency of 250 MHz. The device operates on dual power supplies: 1 V for core logic and 3.3 V for I/O interfaces. It utilizes an FCBGA-324 package suitable for surface mount technology. The component is designed for low latency and low power consumption, incorporating internal buffering and flow control credits optimized for large payloads.

Feature Summary

• Supports root-to-peripheral and peer-to-peer data transfers
• Non-blocking switch architecture for high-performance I/O expansion
• Internal buffering and flow control credits optimized for maximum bandwidth

Applications

• PCIe I/O expansion systems
• Server and storage switching applications
• High-performance embedded computing platforms

Procurement Notes

Verify the specific suffix ZCBXG against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as datasheets may vary by revision. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Selection Notes

Select this component when a 3-port, 24-lane PCIe Gen1 switch is required for I/O expansion. Compare against the 89HPES24T3 series if PCIe Gen2 speeds are needed. Verify package availability in FCBGA-324 format. Consider moisture sensitivity levels and reflow soldering profiles during design integration.

Part Context

This part belongs to the 89HPES24 family of PCIe switches from Renesas (formerly IDT). It serves as an I/O expansion solution distinct from the higher-performance 89H24NT6AG2 system interconnect switch. The N3 designation indicates a 3-port configuration, differentiating it from 6-port variants within the same product line.

Replacement Considerations
