89HPES24T6G2ZCAL8

Specialized Overview

The 89HPES24T6G2ZCAL8 is a PCI Express Gen2 switch interface IC manufactured by Renesas Electronics. It provides 24 lanes and 6 ports for high-performance system interconnect switching. The device supports non-blocking throughput with full line rate capability across all ports. It utilizes an FCBGA-324 package designed for surface mount installation. The component operates on a 3.3V supply voltage and includes internal buffering and flow control credits to optimize bandwidth for large payloads. This specific part number is identified as End-of-Life (EOL) status.

Specialized Feature Summary

• Provides deterministic system interconnect switching with 24 PCIe Gen2 lanes and 6 ports
• Supports partitionable switch architecture for true multi-root support
• Includes multiple Nontransparent Bridging (NTB) functions and movable upstream support
• Features onboard DMA support with optimized internal buffering and flow control

Specialized Applications

• High-performance server system interconnect expansion
• Storage area network (SAN) switching applications
• Multi-root I/O virtualization environments

Specialized Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors or verifying last-time buy options. Verify RoHS compliance status, as indicated data suggests non-compliance for this specific suffix. Ensure compatibility with existing PCB footprints before procurement attempts.

Specialized Selection Notes

Select this component only if legacy support for PCIe Gen2 with six downstream ports is required. Compare against newer Gen3/Gen4 alternatives for performance gains. Verify that the 324-ball FCBGA package fits the target board design constraints. Confirm thermal management requirements due to the density of the switching fabric within the limited package size.

Specialized Part Context

This part belongs to the IDT/Renesas 89HPES series of PCIe switches. It is functionally similar to the 89H24NT6AG2 family but differs in packaging and specific feature sets like NTB support. The 'CAL8' suffix typically denotes specific packaging and temperature grade variations within the broader product line.

Specialized Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Consider consulting Renesas official cross-reference tools for updated replacements. Generic PCIe Gen2 switches may serve as functional substitutes if pin-to-pin compatibility is verified.
