89H32NT24AG2ZAHLG8

Overview

The 89H32NT24AG2ZAHLG8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics Corporation. It provides 32 PCIe Gen2 lanes and 24 switch ports within a non-blocking architecture designed for high-performance system interconnect applications. The device supports partitionable switch architecture for multi-root support and includes multiple Nontransparent Bridging (NTB) functions. Key electrical parameters include a maximum clock frequency of 125 MHz, data rates up to 192 Gb/s, and operation with supply voltages of 1 V, 2.5 V, and 3.3 V. The component operates within a temperature range of -40°C to +85°C and is housed in a 484-lead FCBGA package measuring 23.0 x 23.0 mm.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Support for multiple Nontransparent Bridging (NTB) functions
• On-board DMA support with internal buffering and flow control credits

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) infrastructure
• Enterprise computing platforms requiring deterministic latency

Procurement Notes

Verify the specific suffix ZAHLG8 against official Renesas documentation to confirm lead-free status and packaging type. Check current product status as many variants in this series are marked obsolete. Ensure moisture sensitivity level (MSL 4) handling requirements are met during assembly. Confirm RoHS compliance status through the manufacturer's latest datasheet or PCN notices.

Selection Notes

Select this component when 24 ports of PCIe Gen2 connectivity are required with non-blocking throughput. Consider the 484-FCBGA package size for PCB layout constraints. Evaluate power supply requirements for 1V, 2.5V, and 3.3V rails. Verify thermal management capabilities for the specified operating temperature range. Compare against newer PCIe generations if future scalability is needed.

Part Context

This part belongs to the 89H32NT24 family of PCIe switches from Renesas (formerly IDT). It shares architectural features with other models like the 89H24NT24 and 89H24NT6, differing primarily in lane and port counts. The family is designed for deterministic system interconnect switching with low latency and low power consumption characteristics typical of enterprise-grade PCIe switches.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Users should consult Renesas for current equivalent products or design-in alternatives. Cross-referencing with similar IDT/Renesas PCIe switch families may be necessary for pin-compatible replacements.
