89H16NT16G2ZBHL8

Overview

The Renesas Electronics Corporation 89H16NT16G2ZBHL8 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 (Commercial grade) and supports power supplies of 1V, 2.5V, and 3.3V. The component is housed in a 324-FCBGA package measuring 19x19 mm and utilizes a reel carrier type.

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 optimized for large payloads.

Applications

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

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and standard supply channels may not stock new units. Verification of authenticity and condition is critical when sourcing from secondary markets. Compliance status varies by specific suffix; this specific part number indicates lead-free status is not guaranteed compared to G-suffixed variants. Confirm RoHS compliance requirements against available inventory data before procurement planning.

Selection Notes

Select this model for applications requiring a 16-lane, 16-port PCIe Gen2 switch with non-blocking performance. Ensure the design accommodates the 324-FCBGA package dimensions and thermal requirements. Verify that the commercial temperature grade (-40°C to +85°C) meets environmental specifications. Consider alternative packages or suffixes if reel packaging is required instead of tray, or if industrial temperature grades are necessary.

Part Context

The 89H16NT16G2 series belongs to the IDT/Renesas 89HPES16N family of PCI Express switches. This specific variant, ZBHL8, denotes a commercial temperature grade, lead-free composition, and reel packaging format. It is functionally equivalent to other suffixes within the same family, differing primarily in packaging and environmental compliance attributes rather than core electrical performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly documented in the provided source material. Users should consult official Renesas documentation for current replacement recommendations or cross-reference with the broader 89HPES16N family members, noting differences in temperature grade and packaging.
