89H16NT16G2ZCHLI8

Overview

The 89H16NT16G2ZCHLI8 is a specialized PCI Express switch interface integrated circuit manufactured by Renesas Electronics Corporation. It provides 16 PCIe Gen2 lanes and 16 ports for high-performance, deterministic system interconnect switching. The device operates with a 3.3V supply voltage and utilizes a 324-FCBGA package measuring 19x19 mm. It supports non-blocking throughput for multiple traffic flows regardless of switch loading. The component is classified as obsolete and does not comply with RoHS specifications.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream configurations

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• PCIe Gen2 network infrastructure

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. Compliance status indicates non-compliance with RoHS standards. Engineers should confirm moisture sensitivity level MSL 4 handling requirements during procurement and storage verification processes.

Selection Notes

Designers requiring this specific 16-lane, 16-port PCIe Gen2 switch must account for its obsolete status. Alternative solutions from the same family or newer generations should be evaluated for long-term supply stability. Package compatibility with the 324-FCBGA footprint and 3.3V power domain remains a primary selection constraint for existing designs.

Part Context

This part belongs to the 89HPES16NT16G2 series of PCI Express switches originally developed by Integrated Device Technology, now part of Renesas Electronics. The suffix ZCHLI8 denotes specific packaging and compliance variations within the product line. The series was designed to provide low latency and low power consumption for demanding interconnect applications.

Replacement Considerations

Public confirmed substitute part numbers include 89H16NT16G2ZAHLI8 and 89H16NT16G2ZBHLI8. These variants share the same core switching functionality but may differ in lead-free status or packaging type. Verify pinout and electrical characteristics before substitution.
