89H32NT24BG2ZCHLG8

Overview

The Renesas 89H32NT24BG2ZCHLG8 is a PCIe Gen2 system interconnect switch providing 32 lanes and 24 ports. It operates at a maximum clock frequency of 125 MHz with support for 32/64-bit data buses and a total data rate of 192 Gb/s. The device supports power supply voltages of 1 V, 2.5 V, and 3.3 V. It functions within an operating temperature range of -40°C to +85°C and utilizes a 484-FCBGA package measuring 23x23 mm. This component is classified as a PCI interface IC designed for high-performance switching applications.

Feature Summary

• Non-blocking switch architecture optimized for high performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple nontransparent bridging (NTB) functions
• Features on-board DMA support and internal buffering with flow control credits

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area networks requiring deterministic latency

Procurement Notes

Verify the specific suffix ZCHLG8 against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Confirm current lifecycle status as obsolete or end-of-life through authorized channels before procurement planning. Ensure compatibility with existing PCB footprints for the 484-FCBGA package.

Selection Notes

Select this component when 32 lanes and 24 ports are required for PCIe Gen2 systems. Consider the partitionable architecture if multi-root support is necessary. Verify that the 1V, 2.5V, and 3.3V voltage requirements align with the target board design. Evaluate the 484-FCBGA package constraints for thermal and mechanical integration.
