89H32NT24BG2ZCHLG

Overview

The 89H32NT24BG2ZCHLG is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 PCIe lanes and 24 switch ports within a non-blocking architecture designed for high-performance deterministic switching. The device supports multiple traffic flows with full line-rate throughput regardless of switch loading. It operates at a maximum clock frequency of 125 MHz and supports data rates up to 256 Gb/s. Power supply requirements include 1 V, 2.5 V, and 3.3 V rails. The component is housed in a 484-FCBGA package (23x23 mm) and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports true multi-root functionality through partitionable switch architecture
• Enables movable upstream support and on-board DMA capabilities
• Includes internal buffering and flow control credits optimized for large payloads

Applications

• High-performance server system interconnects
• Storage area network (SAN) switches
• Enterprise networking infrastructure requiring low latency
• Multi-root I/O virtualization environments

Procurement Notes

Verify the specific suffix ZCHLG against official Renesas documentation to confirm lead-free status and industrial temperature grade. Confirm RoHS compliance details directly from the datasheet as distributor listings may vary. Check for end-of-life notices or product change notifications prior to procurement planning.

Selection Notes

Select this component when a high-port-count PCIe Gen2 switch is required for non-blocking bandwidth. Ensure the design accommodates the 484-FCBGA footprint and thermal requirements. Verify that the system power budget aligns with the 1V, 2.5V, and 3.3V supply specifications. Consider pinout compatibility if replacing legacy IDT variants.

Part Context

This part belongs to the 89H32NT series of PCIe switches, which are successors to earlier IDT products acquired by Renesas. It is functionally similar to the 89H32NT24AG2 but may differ in packaging or environmental ratings based on the suffix. The series is designed for scalable enterprise and storage applications requiring deterministic switching performance.

Replacement Considerations

The 89H32NT24AG2ZCHLG is a direct functional equivalent within the same family. Verify pin-to-pin compatibility and electrical parameters before substitution. Other variants in the 89H32NT series may offer different port counts or lane configurations.
