89H32T8G2ZCBL

Overview

The Renesas 89H32T8G2ZCBL is a PCI Express Gen2 switch interface IC designed for high-performance system interconnect applications. It provides 32 PCIe lanes and supports 8 ports, delivering non-blocking throughput with full line rate capabilities. The device operates within a temperature range of -40°C to +85°C and utilizes a 484-FCBGA package measuring 23x23 mm. Key electrical specifications include a maximum clock frequency of 125 MHz and data rates up to 256 Gb/s. Power supply requirements are supported at 1 V, 2.5 V, and 3.3 V levels.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication
• Features internal buffering and flow control credits to maximize bandwidth efficiency

Applications

• High-performance computing server backplanes
• Storage area network infrastructure switches
• Telecommunications base station interconnects

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as documentation may vary by production batch. Check for specific ordering suffixes that denote package variations or environmental ratings. Ensure compatibility with existing PCB footprint designs before procurement.

Selection Notes

Select this model when requiring a dense PCIe Gen2 switching solution with multi-root support capabilities. Consider the 484-FCBGA package constraints during thermal management planning. Evaluate power consumption profiles against system budget requirements. Verify signal integrity needs for 256 Gb/s aggregate throughput in your specific layout design.

Part Context

This component belongs to the IDT/Renesas 89H32 series of PCIe switches, which are widely used in enterprise infrastructure. The part represents a transition from earlier IDT products following Renesas Electronics' acquisition. It serves as a critical node in expanding PCIe topology beyond standard root complex limitations.

Replacement Considerations

Direct replacements include the 89H32T8G2ZCBLI variant, which shares identical functional specifications but may differ in packaging or environmental certification. Cross-reference pinouts and electrical characteristics carefully when substituting.
