89H32NT24AG2ZBHLI

Overview

The Renesas 89H32NT24AG2ZBHLI is a PCIe Gen2 system interconnect switch providing 32 lanes and 24 ports. It features a non-blocking architecture optimized for high-performance deterministic switching with full line-rate throughput. The device supports partitionable architecture for multi-root configurations and includes multiple Nontransparent Bridging (NTB) functions. Key technical specifications include a maximum clock frequency of 125 MHz, data rates up to 192 Gb/s, and support for 32/64-bit data bus widths. Operating voltages are specified at 1 V, 2.5 V, and 3.3 V. The component operates within a temperature range of -40°C to +85°C and is housed in a 484-FCBGA package.

Feature Summary

• Non-blocking switch architecture ensuring full line-rate throughput for multiple traffic flows regardless of load.
• Partitionable switch design enabling true multi-root support and flexible system configuration.
• Support for multiple Nontransparent Bridging (NTB) functions to isolate domains.
• On-board DMA support and internal buffering with flow control credits optimized for large payloads.

Applications

• High-performance server system interconnects
• Storage area network (SAN) switches
• Multi-root compute node aggregation

Procurement Notes

Verify the specific suffix ZBHLI against official datasheets to confirm lead-free status and packaging type. This part number is listed as obsolete or end-of-life by the manufacturer. Confirm moisture sensitivity level (MSL 4) requirements for storage and handling before procurement. Check for available replacement options from the same product family if new designs are required.

Selection Notes

Select this component when 32 PCIe Gen2 lanes and 24 ports are required for non-blocking switching. Ensure the design supports the 484-FCBGA package dimensions and thermal requirements. Verify that the system voltage rails match the 1 V, 2.5 V, and 3.3 V specifications. Consider the obsolete status and plan for long-term supply chain risks or alternative sourcing strategies.

Part Context

This device belongs to the 89H32NT24AG2 series of PCIe Gen2 switches. It shares architectural similarities with other models in the family, such as the 89H32NT24AG2ZBHLG8, differing primarily in lead-free compliance and packaging variations. The series is designed for deterministic system interconnect applications requiring high bandwidth and low latency.

Replacement Considerations

Publicly confirmed substitute part numbers include 89H32NT24AG2ZBHLG8 and 89H32NT24AG2ZCHLGI. These variants offer similar functional capabilities but may differ in lead-free status or temperature grade. Verify pin compatibility and electrical specifications before substitution.
