89H24NT24G2ZCHLI8

Overview

The 89H24NT24G2ZCHLI8 is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 PCIe lanes and 24 ports for high-performance data routing. The device supports a maximum clock frequency of 125 MHz with a data rate of 192 Gb/s. It operates on supply voltages of 1 V, 2.5 V, and 3.3 V within an operating temperature range of -40°C to +85°C. The component 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 partitioning
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream configurations
• Includes onboard DMA support with internal buffering and flow control credits

Applications

• High-performance system interconnect switching
• PCIe switch interface implementations
• Multi-root support architectures

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete or end-of-life. Confirm RoHS compliance status, which is marked as non-compliant in available records. Check for moisture sensitivity level requirements prior to handling. Ensure compatibility with existing PCB layouts due to the specific FCBGA package dimensions.

Selection Notes

Select this component when a 24-port PCIe Gen2 solution is required for deterministic switching. Compare against the 89H32NT24BG2ZCHL8 if higher lane counts are needed. Verify that the 324-FCBGA footprint matches the design constraints. Consider the industrial temperature grade (-40°C to +85°C) for environmental suitability.

Part Context

This part belongs to the 89H24NT24G2 series of PCIe switches from Renesas (formerly IDT). It shares architectural similarities with other models in the family but is distinguished by its specific port count and package type. The suffix ZCHLI8 indicates specific packaging and lead-free status variations within the product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Designers should consult Renesas for current generation equivalents or perform a full mechanical and electrical re-validation if considering alternative vendors.
