89H12T3BG2ZBBCI

Overview

The 89H12T3BG2ZBBCI is a PCIe Gen3 switch interface IC manufactured by Renesas Electronics. It features 12 lanes and 12 ports, supporting data rates up to 8 GT/s per lane for a total bandwidth of 96 Gb/s. The device operates with supply voltages of 1 V, 2.5 V, and 3.3 V within an industrial temperature range of -40°C to +85°C. It is housed in a 324-pin FCBGA package (19x19 mm) and supports 32/64-bit data bus widths. This component provides non-blocking switching architecture optimized for high-performance system interconnect applications.

Feature Summary

• Provides deterministic, non-blocking throughput across all ports regardless of switch loading conditions.
• Supports partitionable switch architecture enabling true multi-root support for complex system configurations.
• Integrates internal buffering and flow control credits optimized for maximum bandwidth and large payload transactions.

Applications

• High-performance server system interconnect
• Storage area network (SAN) infrastructure
• Industrial automation controllers

Procurement Notes

Verify the specific suffix ZBBCI against official Renesas documentation to confirm package type and temperature grade. Confirm current lifecycle status as this series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for the 324-FCBGA package before procurement.

Selection Notes

Select this model when 12 independent PCIe Gen3 lanes are required for low-latency switching. Compare against the 89H48H12G2 if higher port density is needed. Verify that the 1V, 2.5V, and 3.3V power domains align with the target system's power management design constraints.

Part Context

This part belongs to the IDT 89H12NT12G2 family of PCIe switches. It serves as a bridge between host processors and peripheral devices in high-throughput environments. The component replaces legacy PCI solutions with scalable PCIe Gen3 connectivity.

Replacement Considerations

Check for direct substitutes within the 89HPES or 89H48 series from Renesas. Verify pin-to-pin compatibility and electrical specifications before considering alternative vendors.
