89H16NT16G2ZBHL

Overview

The Renesas Electronics Corporation 89H16NT16G2ZBHL is a specialized PCI Express switch interface integrated circuit designed for high-performance system interconnect applications. It provides sixteen PCIe Gen2 lanes and sixteen ports, delivering non-blocking throughput with full line rate capabilities regardless of switch loading. The device operates on a 3.3V supply voltage and utilizes a 324-FCBGA package measuring 19x19 mm. It supports surface mount installation and features internal buffering optimized for large payloads. The component is classified as obsolete.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Supports multiple Nontransparent Bridging (NTB) functions
• Enables true multi-root support through partitionable switch architecture
• Includes onboard DMA support and low-latency operation

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Industrial control systems requiring deterministic latency

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types. Compliance status indicates it does not meet RoHS specifications. Moisture sensitivity level is rated at MSL 4. Users must confirm lead-free status and specific revision details before integration.

Selection Notes

Designers should evaluate the transition to newer generations due to the obsolete status of this Gen2 switch. Verify that the 324-FCBGA footprint matches the target PCB layout constraints. Ensure power delivery circuits accommodate the 3.3V requirement. Consider thermal management strategies suitable for the 19x19 mm package dimensions in dense assemblies.

Part Context

This part belongs to the 89HPES16N family of PCI Express switches from Renesas Electronics. It shares architectural similarities with variants like the 89H16NT16G2ZAHLI but differs in specific packaging and compliance suffixes. The family is characterized by its ability to handle multiple traffic flows simultaneously without contention across all sixteen ports.

Replacement Considerations

Public confirmed substitute part numbers include 89H16NT16G2ZAHLI, 89H16NT16G2ZCHLI, and 89H16NT16G2ZAHLG8. These alternatives share the same core switching functionality and package type but may differ in lead-free status or manufacturing origin.
