89H24NT24G2ZAHLGI8

Overview

The Renesas Electronics 89H24NT24G2ZAHLGI8 is a PCIe Gen2 switch interface IC 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

• Provides high-performance, deterministic system interconnect switching across multiple traffic flows.
• Supports non-blocking throughput where all ports receive full line rate regardless of switch loading.
• Features internal buffering and flow control credits optimized for maximum bandwidth and large payloads.

Applications

• High performance system interconnect
• PCIe switch interface

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details as the specific variant may not meet current environmental standards. Validate the exact suffix against official datasheets to ensure correct package and temperature grade specifications before procurement.

Selection Notes

Select this component for applications requiring 24-lane PCIe Gen2 connectivity. Ensure the design accommodates the 324-FCBGA footprint and multi-voltage power domains. Verify that the operating environment stays within the specified industrial temperature range and that board layout supports the required signal integrity for 125 MHz operation.
