89H32NT8AG2ZBHLG8

Overview

The 89H32NT8AG2ZBHLG8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics Corporation. It provides 32 lanes and 8 ports of high-performance, deterministic switching with non-blocking architecture. The device supports full line rate throughput for multiple traffic flows regardless of switch loading. It operates on supply voltages of 1 V, 2.5 V, and 3.3 V. The maximum clock frequency is 125 MHz, supporting a data rate of 256 Gb/s. The component is housed in a 484-FCBGA package measuring 23x23 mm. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture enabling true multi-root support
• Supports multiple Nontransparent Bridging (NTB) functions
• Includes movable upstream support and on-board DMA capabilities

Applications

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

Procurement Notes

Verify the specific suffix ZBHLG8 against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical records indicate variations across similar part numbers. Check current product lifecycle status, as this model may be obsolete or subject to change notifications. Ensure compatibility with required voltage domains before procurement.

Selection Notes

Select this component when 32 lanes and 8 ports are required for PCIe Gen2 applications. Consider the FCBGA package constraints for PCB layout. Evaluate power requirements for 1V, 2.5V, and 3.3V rails. Verify thermal management needs for the specified temperature range. Compare against other models in the 89H32NT series if port count or lane configuration differs.

Part Context

This part belongs to the 89H32NT8AG2 family of PCIe switches. It shares architectural features with variants like 89H32NT24AG2 but offers fewer ports. The manufacturer transitioned from IDT to Renesas Electronics. Similar parts include 89HPES32H8 for Gen1 applications. The device is designed for deterministic low-latency switching in enterprise environments.

Replacement Considerations

Publicly confirmed substitutes include 89H32NT8AG2ZBHLGI8. Verify pinout and electrical specifications before substitution. Other family members like 89H24NT6AG2 offer different port counts. Ensure replacement parts match the required PCIe generation and package dimensions.
