89H32H8G2ZDBLI

Overview

The 89H32H8G2ZDBLI is a PCIe Gen2 switch interface IC manufactured by Renesas Electronics. It provides 32 lanes and 8 ports of high-performance, deterministic system interconnect switching. The device features a non-blocking switch architecture optimized for high throughput. It operates with supply voltages of 1 V, 2.5 V, and 3.3 V. The maximum clock frequency is 125 MHz. Data rates reach up to 256 Gb/s. It is housed in a 484-FCBGA package. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture providing full line rate throughput for multiple traffic flows regardless of switch loading.
• Partitionable switch architecture supporting true multi-root functionality.
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication.

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Data center infrastructure

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Check datasheet revisions for specific electrical characteristics. Confirm package marking codes match the 484-FCBGA specification. Validate RoHS compliance documentation against current regulatory requirements. Ensure handling procedures account for moisture sensitivity levels specified in the manufacturing data.

Selection Notes

Select this component when 32 lanes and 8 ports are required for PCIe Gen2 systems. Consider partitionability needs for multi-root configurations. Verify voltage compatibility with 1 V, 2.5 V, and 3.3 V domains. Assess thermal management capabilities for the FCBGA package within the industrial temperature range. Evaluate latency requirements against the internal buffering specifications.

Part Context

This part belongs to the 89H32T8G2 series of PCIe switches. It shares architectural similarities with other members like the 89H32NT24AG2 but differs in port count. The series targets high-bandwidth interconnect applications requiring deterministic performance. Renesas Electronics continues to support legacy designs using these components.

Replacement Considerations

Public confirmed substitute part numbers are not available. The component is listed as obsolete or discontinued. Designers should evaluate newer generations of PCIe switches from Renesas or other manufacturers that offer compatible pinouts and feature sets.
