89HA0416PSBCGI

Overview

The 89HA0416PSBCGI is a PCI Express switch manufactured by Renesas Electronics Corporation. It belongs to the 89HPES series of interface ICs designed for high-performance I/O expansion and switching functions. The component facilitates data transfers between upstream and downstream ports within PCIe architectures. It is housed in a SBGA-288 package and supports specific humidity sensitivity requirements. This device serves as a critical interconnect solution for expanding PCIe connectivity in embedded systems.

Feature Summary

• Provides high-performance I/O expansion and switching capabilities between PCIe ports
• Supports root-to-peripheral and peer-to-peer data transfer modes
• Optimized internal buffering and flow control credits for bandwidth efficiency

Applications

• PCIe I/O expansion systems
• Embedded computing platforms requiring port multiplication
• Industrial automation controllers with multiple peripheral interfaces

Procurement Notes

Verify end-of-life status and obsolescence notices before procurement planning. Confirm RoHS compliance and moisture sensitivity level (MSL) ratings against storage and reflow soldering requirements. Ensure compatibility with existing PCB footprints and thermal management designs. Check for available engineering samples or legacy stock if immediate production is required.

Selection Notes

Select this component when a robust PCIe switch solution with SBGA-288 packaging is required for dense board layouts. Consider its support for both upstream-to-downstream and peer-to-peer traffic patterns. Evaluate system latency requirements against the device's internal buffering capabilities. Verify that the manufacturer's documentation aligns with specific application signal integrity needs.

Part Context

This part is part of the 89HPES16T4G2 family, which includes various suffixes indicating package types and environmental grades. Renesas Electronics Corporation produces this series to address complex interconnect needs in modern electronic devices. The specific suffix BCGI denotes the package configuration and lead-free status within the broader product line.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 89HPES family. Review updated datasheets for any functional changes in newer revisions. Ensure alternative components meet the same SBGA-288 footprint and electrical specifications.
