89H32NT24AG2ZAHLI

Overview

The 89H32NT24AG2ZAHLI is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 PCIe lanes and 24 switch ports, supporting a data rate of 256 Gb/s with a maximum clock frequency of 125 MHz. The device operates within a temperature range of -40°C to +85°C and utilizes a 484-FCBGA package. Power requirements include supply voltages of 1 V, 2.5 V, and 3.3 V. It features a non-blocking architecture optimized for high-performance system interconnects.

Feature Summary

• Non-blocking switch architecture providing full line-rate throughput for multiple traffic flows regardless of switch loading.
• Partitionable switch architecture enabling true multi-root support for flexible system configurations.
• Support for multiple Nontransparent Bridging (NTB) functions to isolate domains while allowing communication.

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) fabric connections
• Multi-root compute node aggregation

Procurement Notes

Verify the specific suffix ZAHLI against official Renesas documentation to confirm lead-free status and packaging details. Cross-reference the Mouser part number 972-89H32NT24AG2ZAHLI or similar distributor listings for current availability, as this component may be subject to limited supply or end-of-life restrictions. Confirm RoHS compliance status directly from the datasheet before procurement.

Selection Notes

Select this component when designing systems requiring deterministic, low-latency switching between 24 downstream devices and upstream hosts. Ensure the design supports the required 1 V, 2.5 V, and 3.3 V power rails. Verify that the PCB layout accommodates the 484-FCBGA package dimensions and thermal requirements for industrial temperature operation.

Part Context

This part belongs to the 89H32NT24 series of PCIe Gen2 switches. It is functionally related to variants like 89H32NT24BG2ZCHLGI but differs in manufacturing specifications such as lead content and packaging type indicated by the suffix. It serves as a core interconnect solution for expanding PCIe connectivity in enterprise infrastructure.

Replacement Considerations

Direct replacements include other suffixes of the 89H32NT24AG2 family, such as 89H32NT24AG2ZBHLG or 89H32NT24AG2ZCHLG, depending on lead-free requirements. For updated technology, consider migrating to PCIe Gen3 or Gen4 equivalents if bandwidth constraints allow.
