89H32NT8BG2ZCHLI

Overview

The 89H32NT8BG2ZCHLI is a PCI Express switch interface IC manufactured by Renesas Electronics. It supports 32 PCIe Gen2 lanes and provides 8 switch ports. The device operates with a maximum clock frequency of 125 MHz and functions within an industrial temperature range of -40°C to +85°C. Power supply requirements include voltages of 1 V, 2.5 V, and 3.3 V. The component is packaged in a surface-mount SMD/SMT format using a 484-FCBGA (23x23) housing.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple non-transparent bridging (NTB) functions
• Features movable upstream support and on-board DMA capabilities

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Industrial computing environments requiring wide temperature operation

Procurement Notes

This component is identified as obsolete or end-of-life. Availability is restricted, and it may not be sold in all regions. Verification of current stock status and alternative sourcing channels is required before procurement planning. Confirm the specific suffix ZCHLI matches the required package and temperature grade.

Selection Notes

Select this part when a 32-lane, 8-port PCIe Gen2 switch is required for deterministic system interconnect. Ensure the design accommodates the 484-FCBGA footprint and the specified voltage rails. Verify that the industrial temperature range meets the operational environment requirements.

Part Context

This device belongs to the 89H32NT series of PCIe switches from Renesas (formerly IDT). It shares architectural features with other models like the 89H32NT24AG2 but differs in port count. The series is designed for high-throughput applications requiring low latency and internal buffering.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, engineering change orders should reference official Renesas replacement recommendations or equivalent industry components after thorough validation.
