89H24NT24G2ZBHLI

Overview

The Renesas Electronics 89H24NT24G2ZBHLI is a PCI Express Gen2 system interconnect switch providing 24 lanes and 24 ports. It operates with a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. The device utilizes a 32/64-bit data bus width and functions within a temperature range of -40°C to +85°C. Power requirements include supply voltages of 1 V, 2.5 V, and 3.3 V. It is housed in a 324-FCBGA package (19x19 mm) designed for surface mount installation.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple non-transparent bridging (NTB) functions for isolated domain communication

Applications

• High-performance server system interconnect switching
• Multi-root storage area network (SAN) topologies
• Enterprise infrastructure requiring deterministic low-latency data transfer

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require verifying specific lot dates or secondary market suppliers. Engineers should confirm current stock status directly with authorized distributors before design finalization due to potential discontinuation risks.

Selection Notes

Select this part when a 24-port PCIe Gen2 switch with partitionable architecture is required. Verify that the 324-FCBGA footprint fits the PCB layout constraints. Ensure the design accommodates the three distinct voltage domains (1V, 2.5V, 3.3V) and meets the thermal dissipation requirements for the commercial temperature grade (-40°C to +85°C).

Part Context

This model belongs to the 89H24NT24G2 series of PCIe switches from Renesas. It shares architectural similarities with other parts in the family but differs in pinout, packaging, and specific feature enablement codes. The suffix ZBHLI indicates specific lead-free status, temperature grade, and packaging configuration unique to this identifier.

Replacement Considerations

Direct replacements are limited due to the obsolete status. Consider evaluating newer generations such as PCIe Gen3 or Gen4 switches from Renesas or competitors if form-factor compatibility allows. Cross-referencing electrical specifications and pinouts is essential when migrating to alternative components.
