89H32H8G3YCHLGI

Overview

The 89H32H8G3YCHLGI is a PCI Express system interconnect switch manufactured by Renesas Electronics Corporation. It provides 32 PCIe Gen2 lanes and 8 ports of high-performance, deterministic switching. The device features a non-blocking architecture optimized for maximum bandwidth and large payloads, supporting internal buffering and flow control credits. It operates within a temperature range of -40°C to +85°C and utilizes a 484-FCBGA package with dimensions of 23x23 mm. Key electrical parameters include support for 1V, 2.5V, and 3.3V power supplies, a maximum clock frequency of 125 MHz, and a data rate of 256 Gb/s.

Feature Summary

• Non-blocking switch architecture ensuring full line-rate throughput for multiple traffic flows regardless of switch loading.
• Partionable switch architecture enabling true multi-root support for flexible system configurations.
• Supports multiple non-transparent bridging functions (NTB) and movable upstream capabilities.
• Includes on-board DMA support and internal buffering with flow control credits for low latency.

Applications

• High-performance server system interconnect
• Storage area network (SAN) switches
• Industrial automation control systems

Procurement Notes

Verify the specific suffix 'YCHLGI' against official Renesas documentation to confirm exact moisture sensitivity level, lead-free status, and packaging type. Confirm current product lifecycle status as some variants in this family are obsolete or end-of-life. Ensure compatibility with existing PCB footprint and thermal requirements before procurement.

Selection Notes

Select this component when a high-port-count PCIe Gen2 switch with non-blocking performance is required. Compare against other models in the 89H32 series based on port count and lane configuration. Verify that the 484-FCBGA package fits the design constraints and that the operating temperature range meets environmental specifications.

Part Context

This part belongs to the Renesas 89H32 series of PCIe switches, designed for demanding enterprise and industrial applications. It is related to other variants such as the 89H32H8G3YBHLG and 89H32NT8BG2ZAHLGI, which share similar core architectures but may differ in pinout, packaging, or specific feature sets. Always consult the latest datasheet for precise differentiation between suffixes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Check Renesas official documentation for direct replacements or updated series recommendations, as older PCIe Gen2 switches may be phased out in favor of newer generations.
