89H12NT12G2ZBHLI8

Overview

The Renesas 89H12NT12G2ZBHLI8 is a PCIe switch interface IC providing 12 lanes and 12 ports. It operates at a maximum clock frequency of 125 MHz with a data rate of 96 Gb/s. The device supports multiple power supply voltages: 1 V, 2.5 V, and 3.3 V for both minimum and maximum specifications. It functions within an operating temperature range of -40°C to +85°C. The component utilizes a 324-FCBGA package (19x19 mm) and features a 32/64-bit data bus width. It is classified as a Gen2 PCI Interface IC.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports true multi-root functionality through partionable switch architecture
• Includes multiple Nontransparent Bridging (NTB) functions and movable upstream support

Applications

• High-performance system interconnect switching
• Multi-root server architectures requiring deterministic throughput
• On-board DMA applications with internal buffering

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or secondary market sources. Confirm RoHS compliance status, as listings indicate non-compliance in some records. Ensure the specific suffix ZBHLI8 matches the required packaging format, such as cut tape or reel, before procurement.

Selection Notes

Select this model when a 12-lane PCIe Gen2 switch with non-blocking throughput is required. Verify that the 324-FCBGA footprint fits the PCB layout constraints. Check compatibility with 1V, 2.5V, and 3.3V power domains. Consider the obsolete status and lead times associated with end-of-life components during design-in phases.

Part Context

The 89H12NT12G2ZBHLI8 belongs to the 89H12N series of PCIe switches from Renesas Electronics. It shares architectural similarities with other models like the 89H16NT16G2 series but differs in lane count and port configuration. The 'Z' suffix typically denotes RoHS compliance variations, while 'BHLI8' specifies the specific package and tape/reel configuration details.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may require verification against newer Renesas PCIe switch families or alternative manufacturers.
