89H32T8G2ZCBLI

Overview

The Renesas 89H32T8G2ZCBLI is a PCI Express Gen2 switch interface IC designed for high-performance system interconnect applications. It provides 32 lanes and 8 ports, supporting a maximum clock frequency of 125 MHz with a data rate of 256 Gb/s. The device operates within a temperature range of -40°C to +85°C and utilizes multiple power supply voltages including 1 V, 2.5 V, and 3.3 V. Packaged in a 484-FCBGA format (23x23 mm), it supports surface mount installation. This component is classified as an I/O expansion switch intended for PCIe architectures requiring non-blocking throughput.

Feature Summary

• Features non-blocking switch architecture optimized for high performance and large payloads
• Includes internal buffering and flow control credits to maximize bandwidth efficiency

Applications

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

Procurement Notes

Verify the current lifecycle status before integration, as this specific part number is listed as obsolete or end-of-life by the manufacturer. Confirm RoHS compliance details directly with authorized distributors, as records indicate varying statuses. Ensure compatibility with existing PCB footprints for the 484-FCBGA package. Check for moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this component when designing systems requiring PCIe Gen2 connectivity with 32 lanes and 8 ports. Ensure the design supports the required 1 V, 2.5 V, and 3.3 V power rails. Verify that the thermal management solution accommodates the operating temperature range of -40°C to +85°C. Consider the 484-FCBGA package constraints for layout and routing complexity compared to lower pin-count alternatives.

Part Context

This device belongs to the Renesas 89H32T8G2 series of PCI Express switches. It is functionally similar to other variants such as the 89H32NT8AG2ZCHL8 and 89H32NT8BG2ZCHLGI8, which share the same lane count and port configuration. These components are part of the broader IDT/Renesas portfolio for PCIe interconnect solutions, often replacing legacy parts from Integrated Device Technology.

Replacement Considerations

Potential substitutes include the 89H32NT8AG2ZCHL8 and 89H32NT8BG2ZCHLGI8. Verify pin-to-pin compatibility and electrical specifications before substitution. Note that these alternative part numbers may also be subject to obsolescence or limited availability.
