89H64H16G3ZABLG

Specialized Overview

The 89H64H16G3ZABLG is a PCIe Gen3 switch IC providing 64 lanes and 16 ports. It features a non-blocking architecture optimized for high-performance system interconnects with partitionable support for multi-root configurations. Internal buffering and flow control credits are included to maximize bandwidth and handle large payloads efficiently. The device operates at a maximum clock frequency of 125 MHz with a data rate of 256 Gb/s. Power supply requirements include 1 V, 1.5 V, and 3.3 V rails. It functions within an operating temperature range of 0°C to +70°C and is housed in an FCBGA-1156 package.

Specialized Feature Summary

• Provides deterministic system interconnect switching with full line-rate, non-blocking throughput across all ports regardless of switch loading.
• Supports true multi-root architectures through a partitionable switch design.
• Optimizes internal buffering and flow control credits to accommodate maximum bandwidth and large payload sizes.

Specialized Applications

• High-performance server system interconnects
• Storage area network (SAN) infrastructure
• Enterprise networking equipment

Specialized Procurement Notes

Verify component authenticity through authorized Renesas distributors or direct manufacturer channels. Confirm the specific suffix ZABL indicates lead-free status and RoHS compliance as per official datasheets. Check current lifecycle status as this series may be discontinued or subject to limited availability. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Specialized Selection Notes

Select this component when designing systems requiring 64 PCIe Gen3 lanes with low latency and high reliability. Compare against Gen2 variants if bandwidth requirements are lower. Verify power budget constraints for the 1V, 1.5V, and 3.3V domains. Ensure the FCBGA-1156 footprint fits the target PCB layout and thermal management strategy.
