89H32T8G2ZCBLG8

Overview

The Renesas 89H32T8G2ZCBLG8 is a PCIe Gen2 switch interface IC designed for high-performance system interconnect applications. It provides 32 lanes and 8 ports, supporting data rates up to 5 Gbps per lane with a total bandwidth of 256 Gb/s. The device operates within a temperature range of -40°C to +85°C and utilizes a 484-FCBGA package measuring 23x23 mm. Power supply requirements include 1 V, 2.5 V, and 3.3 V rails. The component supports surface mount installation and features internal buffering and flow control credits optimized for large payloads.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple traffic flows regardless of switch loading.
• Partitionable switch architecture enabling true multi-root support for flexible system configurations.
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication.

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) infrastructure
• Industrial automation control systems

Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation to confirm RoHS compliance and lead-free status, as suffixes often denote environmental or packaging variations. Confirm current lifecycle status, as similar models in this series are marked obsolete. Ensure compatibility with existing PCB footprints for the 484-FCBGA package before procurement.

Selection Notes

Select this model when 32 lanes and 8 ports are required for PCIe Gen2 connectivity. Compare against the 89H32NT24AG2 if 24 ports are needed instead. Verify voltage levels match the target system's 1V, 2.5V, and 3.3V supplies. Consider thermal management requirements for the FCBGA package in dense enclosures.

Part Context

This component belongs to the Renesas 89H32T8G2 series of PCIe switches. It shares architectural similarities with other members like the 89H32NT24AG2 but differs in port count and specific feature sets. The series is designed for deterministic low-latency switching in enterprise and industrial environments.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model are not available in the provided source material. Check for direct pin-compatible alternatives within the same Renesas family only if officially documented.
