89H32NT24BG2ZCHLGI

Overview

The Renesas 89H32NT24BG2ZCHLGI is a PCIe Gen2 system interconnect switch providing 32 lanes and 24 ports. It operates with a maximum clock frequency of 125 MHz and supports data rates up to 256 Gb/s. The device utilizes a non-blocking architecture optimized for high-performance deterministic switching. It requires supply voltages of 1 V, 2.5 V, and 3.3 V. Operating temperatures range from -40°C to +85°C. The component is housed in a 484-lead FCBGA package measuring 23x23 mm. It features internal buffering, flow control credits, and on-board DMA support.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple traffic flows regardless of load.
• Partitionable switch design enabling true multi-root support and flexible system configuration.
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication.

Applications

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

Procurement Notes

Verify the specific suffix ZCHLGI against official Renesas documentation to confirm lead-free status and industrial temperature grade. Confirm RoHS compliance details directly with the manufacturer as regulatory statuses can change. Check for any product change notices or end-of-life announcements prior to procurement decisions.

Selection Notes

Select this component when a high-port-count PCIe Gen2 switch is required for deterministic latency. Ensure the design accommodates the 484-FCBGA footprint and thermal requirements. Verify that the system power budget supports the 1V, 2.5V, and 3.3V rails simultaneously.

Part Context

This part belongs to the 89H32NT24BG2 series of PCIe switches. It is functionally similar to variants like 89H32NT24AG2 but differs in manufacturing specifications such as lead content and temperature grade. The 'G2' designation indicates PCIe Generation 2 compatibility.
