89H12NT12G2ZBHLG

Overview

The 89H12NT12G2ZBHLG is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, functioning as a PCI Express switch. It provides 12 PCIe Gen2 lanes and 12 switch ports within a non-blocking architecture designed for high-performance system interconnect partitioning. The device supports true multi-root capabilities through its partitionable switch architecture and includes multiple Nontransparent Bridging (NTB) functions. It operates with a supply voltage of 3.3V and utilizes a 324-FCBGA package measuring 19x19 mm. The component is classified as obsolete.

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on secondary market distributors or surplus suppliers rather than direct manufacturing channels. Confirm the specific suffix ZBHLG matches the required package and temperature grade, as ordering suffixes define physical attributes. Ensure compatibility with existing PCB footprints for the 324-FCBGA format before procurement.

Selection Notes

Select this part when designing systems requiring 12-port PCIe Gen2 switching with non-blocking throughput. It is suitable for applications needing partitionable architectures for multi-root support. Verify that the 3.3V supply requirement aligns with the system power design. Consider the FCBGA package size constraints during layout planning.

Part Context

The 89H12NT12G2ZBHLG belongs to the 89H12N family of PCI Express switches from Renesas. This series is engineered for high-bandwidth data transfer in complex computing environments. The specific model integrates advanced flow control credits to optimize bandwidth for large payloads while maintaining low latency.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is obsolete, alternative solutions require manual evaluation of pin compatibility and functional equivalence with newer Renesas PCIe switch models.
