89H16NT16G2ZBHLG8

Overview

The Renesas Electronics Corporation 89H16NT16G2ZBHLG8 is a specialized PCI Express switch interface integrated circuit. It provides sixteen PCIe Gen2 lanes and sixteen ports for high-performance, deterministic system interconnect switching. The device features a non-blocking architecture optimized for multiple traffic flows with full line-rate throughput regardless of switch loading. It operates within a temperature range of -40°C to +85°C and supports power supply voltages of 1V, 2.5V, and 3.3V. The component is housed in a 324-FCBGA package measuring 19x19 mm.

Feature Summary

• Non-blocking switch architecture ensuring full line-rate throughput for multiple simultaneous traffic flows.
• Partionable switch architecture enabling true multi-root support capabilities.
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication.
• Includes onboard DMA support and internal buffering with flow control credits.

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area network (SAN) connectivity

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus channels. Confirm RoHS compliance status, as specific suffixes indicate varying environmental compliance levels. Ensure the specific package type matches design requirements before procurement.

Selection Notes

Select this part for applications requiring a 16-lane, 16-port PCIe Gen2 switch topology. Verify that the 324-FCBGA footprint fits the PCB layout constraints. Consider the operating temperature grade if the deployment environment exceeds standard commercial limits. Check for compatible replacement packages if lead-free variants are required.

Part Context

This device belongs to the 89HPES16NT16G2 family of PCI Express switches manufactured by Renesas Electronics. It is designed to replace legacy interconnect solutions with scalable, high-bandwidth switching capabilities. The product line emphasizes low latency and power efficiency for enterprise and industrial computing systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must evaluate alternative PCIe switch ICs from current Renesas portfolios or other manufacturers that match the lane count and port configuration requirements.
