89H12NT12G2ZAHL

Overview

The 89H12NT12G2ZAHL is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 12 PCIe Gen2 lanes and 12 switch ports, delivering high-performance, deterministic switching with full line-rate, non-blocking throughput for multiple traffic flows. The device operates within a temperature range of -40°C to +85°C and supports supply voltages of 1 V, 2.5 V, and 3.3 V. It utilizes a 324-FCBGA package (19x19 mm) with a maximum clock frequency of 125 MHz and a data rate of 96 Gb/s. The component features a 32/64-bit data bus width and is classified as a specialized interface IC.

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus channels. Ensure compatibility with existing PCB footprints and verify RoHS compliance status through official documentation before procurement planning.

Selection Notes

Select this part when a 12-port, 12-lane PCIe Gen2 solution is required for non-blocking switching. Consider the 324-FCBGA package constraints and thermal requirements for industrial temperature ranges. Evaluate alternative models from the same family if higher lane counts or different port configurations are needed.

Part Context

The 89H12NT12G2ZAHL belongs to the 89HPES series of PCIe switches from Renesas (formerly IDT). This series focuses on providing scalable, low-latency interconnect solutions for enterprise and industrial computing environments. The specific model offers a balanced configuration of 12 lanes and ports for mid-range switching needs.

Replacement Considerations

Public confirmed substitute part numbers include 89H12NT12G2ZCHLGI8 and 89H12NT12G2ZAHLI8. Verify pinout and electrical specifications against the original datasheet before substitution.
