89H12T3BG2ZBBC

Overview

The 89H12T3BG2ZBBC is a PCI Express switch interface IC manufactured by Renesas Electronics. It supports 12 PCIe Gen2 lanes and provides 12 switch ports with non-blocking throughput. The device operates at a maximum clock frequency of 125 MHz and delivers a data rate of 96 Gb/s. It features a 32/64-bit data bus width and requires supply voltages of 1 V, 2.5 V, and 3.3 V. The component is housed in a 324-FCBGA package (19x19 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
• Supports multiple Nontransparent Bridging (NTB) functions for true multi-root capability
• Includes onboard DMA support and internal buffering with flow control credits

Applications

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

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation to ensure compatibility with specific voltage and thermal requirements. Confirm end-of-life status and availability through authorized distributors, as this component may be subject to discontinuation notices or limited stock constraints.

Selection Notes

Select this component when a 12-lane PCIe Gen2 switch with non-blocking performance is required. Ensure the design accommodates the 324-FCBGA package footprint and the necessary 1V, 2.5V, and 3.3V power rails. Verify that the application benefits from the supported Nontransparent Bridging and onboard DMA features.

Part Context

This part belongs to the 89H12NT12G2 series of PCIe switches. It shares architectural similarities with other members like the 89H12NT12G2ZCHLGI8 but differs in packaging and specific suffix configurations. The series is designed for deterministic system interconnect switching with low latency and low power consumption characteristics.

Replacement Considerations

Check for direct substitutes within the 89H12NT12G2 family. Verify pin-to-pin compatibility and electrical parameter alignment before considering alternative vendors.
