89HPES12T3G2ZABC

Specialized Overview

The 89HPES12T3G2ZABC is a PCI Express switch interface integrated circuit manufactured by Renesas Electronics Corporation. It belongs to the PRECISE series and provides high-performance I/O expansion capabilities. The device features a switch architecture optimized for connecting one upstream port to two downstream ports, supporting root-to-peripheral and peer-to-peer data transfers. It operates on a 3.3V supply voltage and is housed in a 324-CABGA package with dimensions of 19x19 mm. The component utilizes surface mount technology for installation.

Specialized Feature Summary

• Switch architecture optimized for I/O expansion between upstream and downstream ports
• Supports internal buffering and flow control credits for large payloads
• Enables low latency and low power operation

Specialized Applications

• PCI Express switch interface applications
• I/O expansion systems requiring root-to-peripheral connectivity
• Peer-to-peer switching between downstream ports

Specialized Procurement Notes

Verify component authenticity through authorized Renesas distributors or official channels. Confirm RoHS compliance status as documentation may vary by production batch. Check moisture sensitivity level handling requirements prior to assembly. Ensure the specific suffix matches design specifications for pinout and electrical characteristics.

Specialized Selection Notes

Select this component when a three-port PCIe Gen2 switch solution is required for system interconnect. Compare against the 89HPES24T3G2ZCAL8 for higher lane counts. Verify compatibility with existing PCB layout constraints due to the 324-CABGA package size. Ensure thermal management strategies align with the device's power consumption profile.

Specialized Part Context

This part is part of the 89HPES12 family, which includes variants like 89HPES12NT3ZBBC and 89HPES12N3AZCBCG. These components share similar functional architectures but differ in packaging, suffix codes, and availability status. Some family members are marked as obsolete or end-of-life, necessitating careful verification of current stock and long-term supply viability.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the 89HPES24T3G2ZCAL8 for expanded lane requirements or consulting Renesas for current active replacements within the PRECISE series.
