89H16NT16G2ZBHLI8

Overview

The Renesas Electronics Corporation 89H16NT16G2ZBHLI8 is a specialized PCI Express switch interface integrated circuit. It provides sixteen PCIe Gen2 lanes and sixteen ports for high-performance, deterministic system interconnect switching. The device features a non-blocking architecture optimized for multiple traffic flows with full line-rate throughput regardless of switch loading. It operates within a temperature range of -40°C to +85°C and supports power supply voltages of 1V, 2.5V, and 3.3V. The component utilizes a 324-FCBGA package with dimensions of 19x19 mm and has a maximum clock frequency of 125 MHz.

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or end-of-life inventory. Ensure compliance with RoHS status indicated in official documentation, as this specific suffix may not meet current environmental regulations. Confirm moisture sensitivity level MSL 4 handling requirements during procurement and storage.

Selection Notes

Select this part only if legacy compatibility with PCIe Gen2 specifications is required. Verify that the 324-FCBGA footprint matches the PCB design constraints. Consider the industrial temperature grade for environmental suitability. Evaluate alternative newer generation switches if performance scalability or updated regulatory compliance is necessary for the target application.
