89H12NT12G2ZBHL8

Overview

The Renesas 89H12NT12G2ZBHL8 is a PCIe Gen2 system interconnect switch providing 12 lanes and 12 ports. It operates with supply voltages of 1 V, 2.5 V, and 3.3 V, supporting a maximum clock frequency of 125 MHz and a data rate of 96 Gb/s. The device utilizes a 324-FCBGA package (19x19 mm) for surface mount installation. It functions within an operating temperature range of -40°C to +85°C 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 for true multi-root capability
• Features internal buffering and flow control credits optimized for large payloads

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Deterministic low-latency data routing

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements as specific suffixes may vary in regulatory adherence. Check moisture sensitivity level handling procedures before assembly to prevent damage during reflow soldering processes.

Selection Notes

Select this model when 12-port non-blocking connectivity is required for PCIe Gen2 environments. Ensure board design accommodates the 324-FCBGA footprint and thermal dissipation needs. Verify that upstream and downstream link speeds match the 5.0 GT/s specification for optimal performance.
