89H48H12G2ZCBLG

Overview

The 89H48H12G2ZCBLG is a PCI Express switch interface integrated circuit manufactured by Renesas Electronics Corporation. It provides 48 PCIe Gen2 lanes and 12 ports for high-performance system interconnect switching. The device operates with a supply voltage of 3.3V and utilizes a 676-FCBGA package measuring 27x27 mm. It supports non-blocking throughput and internal buffering optimized for large payloads. The component is classified as obsolete status.

Feature Summary

• Non-blocking switch architecture providing full line rate throughput for multiple traffic flows regardless of switch loading.
• Partionable switch architecture designed to support true multi-root configurations.
• Internal buffering and flow control credits optimized for maximum bandwidth and large payload sizes.

Applications

• High performance system interconnect switching
• Multi-root server architectures
• Storage area network (SAN) switches

Procurement Notes

This component has an official obsolete status from the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types such as tape and reel variants. Confirm RoHS3 compliance and moisture sensitivity level 4 handling requirements during procurement and storage.

Selection Notes

Select this part for applications requiring 48 lanes and 12 ports of PCIe Gen2 connectivity. Ensure the design accommodates the 676-FCBGA footprint and 3.3V power domain. Consider the obsolete status when planning long-term production lifecycles and verify compatibility with existing root complex hardware.

Part Context

The 89H48H12G2ZCBLG belongs to the 89HPES48H12G2 family of PCIe switches. It shares architectural features with other models in the series, such as the 89H48H12G2ZCBLGI, differing primarily in temperature grade and lead-free status suffixes. This specific variant targets commercial temperature ranges.

Replacement Considerations

Public confirmed substitute part numbers include 89H48H12G2ZCBLGI and 89H48H12G2ZCBLG8. Verify pinout compatibility and electrical specifications before substitution due to potential differences in temperature grades and packaging formats.
