89HPES22H16ZABLI8

Overview

The 89HPES22H16ZABLI8 is a PCIe system interconnect switch manufactured by Renesas Electronics Corporation. It provides 22 PCIe Gen1 lanes and 16 switch ports, utilizing a non-blocking architecture optimized for high-performance system interconnect applications. The device supports partitionable switch architecture for true multi-root support and includes internal buffering with flow control credits to maximize bandwidth and handle large payloads. It operates at a maximum clock frequency of 125 MHz and supports power supply voltages of 1 V, 2.5 V, and 3.3 V. The component is housed in a 484-lead FCBGA package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides deterministic system interconnect switching with full line rate, non-blocking throughput across all ports regardless of switch loading.
• Supports partitionable switch architecture enabling true multi-root configurations for flexible system design.
• Integrates internal buffering and flow control credits optimized for maximum bandwidth and large payload transfers.

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• I/O expansion systems requiring low latency

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that the specific suffix ZABLI8 matches the required package type (FCBGA) and temperature grade (Industrial). Check for available replacement options from Renesas or compatible third-party switches if long-term supply assurance is required for production.

Selection Notes

Select this component when a high port count with non-blocking performance is required for PCIe Gen1 systems. Ensure the design accommodates the 484-lead FCBGA package constraints. Verify that the application benefits from multi-root support and internal flow control features rather than simpler I/O expansion needs which might be served by lower-port-count devices.

Part Context

This part belongs to the 89HPES series of PCIe switches from Renesas (formerly IDT). It is positioned as a high-end solution for system interconnect, distinct from lower-port I/O expansion switches like the 89HPES16T7. The series emphasizes deterministic latency and high bandwidth for complex computing environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is marked obsolete, consult Renesas for current recommended replacements or equivalent family members with updated availability.
