89H12NT12G2ZBHL

Overview

The 89H12NT12G2ZBHL is a PCI Express switch interface integrated circuit manufactured by Renesas Electronics Corporation. It provides 12 PCIe Gen2 lanes and 12 switch ports, delivering non-blocking throughput for multiple traffic flows. The device operates with maximum clock frequencies of 125 MHz and supports power supply voltages of 1 V, 2.5 V, and 3.3 V at both minimum and maximum levels. It is housed in a surface-mount SMD/SMT package and functions within an operating temperature range from -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication

Applications

• High-performance system interconnect switching
• Multi-root server architectures requiring partitionable switching
• Network infrastructure equipment utilizing PCIe Gen2 standards

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and it may not be sold in all regions through standard distributors. Verification of current stock status and alternative sourcing channels is required before procurement planning. Compliance with RoHS directives should be confirmed against specific manufacturing dates due to the product's age.

Selection Notes

Designers must account for the discontinued status when selecting this part for new hardware. The 324-FCBGA package requires specialized PCB layout considerations for thermal management and signal integrity. Ensure that the supporting system design accommodates the specific voltage rails of 1 V, 2.5 V, and 3.3 V. Legacy support constraints should be evaluated against long-term maintenance requirements.

Part Context

This part belongs to the 89H12N family of PCI Express switches. It shares architectural similarities with other models like the 89H16NT16G2ZBHLI but differs in lane count and port configuration. The suffix indicates specific packaging and compliance variations within the broader IDT/Renesas portfolio of PCIe interconnect solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements are not explicitly listed. Engineers should consult official Renesas resources for potential next-generation alternatives or compatible interface controllers.
