89H12NT12G2ZCHLGI

Overview

The 89H12NT12G2ZCHLGI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 12 lanes and 12 ports with non-blocking architecture for high-performance data transfer. The device supports a maximum clock frequency of 125 MHz and operates within a temperature range of -40°C to +85°C. Power requirements include voltages of 1 V, 2.5 V, and 3.3 V. It utilizes a 324-FCBGA package (19x19 mm) with surface mount installation. The component features a data rate of 96 Gb/s and supports 32/64-bit data bus widths.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream capabilities
• Includes on-board DMA support with internal buffering and flow control credits

Applications

• High-performance computing system interconnects
• Multi-root server architectures requiring deterministic switching
• Industrial control systems demanding low latency

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints for the 324-FCBGA package. Check for RoHS3 compliance documentation if required by regional regulations. Validate lead-free specifications against current manufacturing standards.

Selection Notes

Select this model when 12 independent PCIe Gen2 ports are required without bandwidth contention. Consider the FCBGA package constraints for thermal management and board space. Evaluate the need for NTB functionality if isolated domain communication is necessary. Assess power supply complexity due to multiple voltage domains (1V, 2.5V, 3.3V). Compare against higher-lane alternatives if future scalability is anticipated.

Part Context

This part belongs to the 89H12NT12G2 series of PCIe switches. It shares architectural similarities with other models in the family but offers a specific 12-lane configuration. The suffix ZCHLGI indicates specific packaging and environmental attributes defined by the manufacturer. It serves as a specialized interface IC for connecting multiple PCIe endpoints.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT89H12NT12G2ZCHLGI. Verify pin-to-pin compatibility and electrical parameters before substitution. Cross-reference datasheets for any minor revisions in the 89H12NT12G2 series.
