89H32NT8BG2ZCHL

Overview

The 89H32NT8BG2ZCHL is a PCI Express switch interface IC manufactured by Renesas Electronics. It provides 32 lanes and 8 ports for high-performance system interconnect switching. The device supports PCIe Gen2 speeds with a maximum clock frequency of 125 MHz. It operates within a temperature range of -40°C to +85°C and requires supply voltages of 1V, 2.5V, and 3.3V. The component is packaged in an SMD/SMT format using a 484-FCBGA (23x23) housing. This product is currently listed as obsolete.

Feature Summary

• Non-blocking switch architecture optimized for high performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple nontransparent bridging functions (NTB)
• Features on-board DMA support and internal buffering with flow control credits

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area networks requiring deterministic latency

Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is restricted, and it may not be sold in all regions through standard channels. Verification of current stock status and end-of-life documentation is required before integration into new designs.

Selection Notes

Engineers should evaluate alternative active components from the same family or newer generations due to the obsolete status of this part. Ensure that the 484-FCBGA footprint and voltage requirements match the target board design if used in legacy maintenance projects.

Part Context

This model belongs to the 89H series of PCIe switches from Renesas (formerly IDT). It shares architectural similarities with other variants like the 89H32NT24AG2 but differs in port count and lane configuration. The suffix indicates specific packaging and environmental compliance details.

Replacement Considerations

Direct public substitutes are not explicitly confirmed in available documentation. Consider reviewing active Renesas PCIe switch models with comparable lane counts and FCBGA footprints for migration.
