89H12NT12G2ZCHL

Overview

The Renesas 89H12NT12G2ZCHL is a PCI Express interface integrated circuit functioning as a PCIe Gen2 switch. It provides 12 lanes and 12 ports for high-performance system interconnect switching. The device supports data rates up to 96 Gb/s with a maximum clock frequency of 125 MHz. It operates within a temperature range of -40°C to +85°C and utilizes a 324-FCBGA package measuring 19x19 mm. Power supply requirements include voltages of 1 V, 2.5 V, and 3.3 V. The component features a non-blocking architecture optimized for deterministic throughput.

Feature Summary

• Non-blocking switch architecture providing full line rate throughput for multiple traffic flows regardless of switch loading.
• Partitionable switch architecture enabling true multi-root support capabilities.
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream configurations.
• Includes on-board DMA support with internal buffering and flow control credits optimized for large payloads.

Applications

• High Performance System Interconnect
• PCIe Switch Interface
• Multi-root Support Systems

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or end-of-life inventory. Ensure compatibility with existing PCB layouts due to the specific 324-FCBGA footprint. Confirm moisture sensitivity level handling procedures during storage and assembly processes.

Selection Notes

Select this part when a 12-lane PCIe Gen2 switch is required for deterministic system interconnect applications. Verify that the design accommodates the 324-FCBGA package dimensions and pitch. Ensure power delivery networks support the specified 1 V, 2.5 V, and 3.3 V rails. Consider the industrial temperature range if operating in harsh environments.
