89H16NT16G2ZAHLI

Overview

The Renesas 89H16NT16G2ZAHLI is a specialized interface integrated circuit designed as a PCIe Gen2 system interconnect switch. It provides 16 lanes and 16 ports for high-performance, deterministic switching with non-blocking throughput. The device operates on a 3.3V supply voltage and utilizes a 324-FCBGA package measuring 19x19 mm. It supports internal buffering, flow control credits, and onboard DMA functions to optimize bandwidth for large payloads. The component is classified as obsolete and does not comply with RoHS standards.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable 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 requiring partitionable switches
• Systems utilizing Nontransparent Bridging (NTB) functions

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types. Compliance status indicates non-compliance with RoHS regulations. Users must confirm the specific moisture sensitivity level and handling requirements prior to procurement attempts.

Selection Notes

Selection should consider the requirement for 16-lane PCIe Gen2 connectivity and the necessity for non-blocking switching performance. The FCBGA package dimensions and pin count must match the target PCB layout. Designers should verify power supply compatibility with the specified 3.3V operation and ensure thermal management aligns with the device's low-latency, low-power characteristics.

Part Context

The 89H16NT16G2ZAHLI belongs to the 89HPES16NT16G2 family of PCIe switches manufactured by Renesas Electronics. This series focuses on providing deterministic system interconnect solutions. The part number suffix 'ZAHLI' typically denotes specific packaging and compliance variations within this product line, distinguishing it from other variants like ZCHLGI or ZBHL.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must evaluate current market offerings for equivalent 16-port PCIe Gen2 switches that meet the required non-blocking and NTB specifications.
