89HPES24T3G2ZCBL

Specialized Overview

The 89HPES24T3G2ZCBL is a PCI interface IC manufactured by Renesas Electronics, belonging to the PRECISE series. It functions as a PCIe Gen2 switch providing 24 lanes across three ports. The device utilizes an FCBGA-676 package with dimensions of 27 x 27 mm and a 1 mm pitch. It operates within a temperature range of -40°C to +85°C and supports surface mount installation. The component requires 1 V and 3.3 V power supplies and features a maximum clock frequency of 125 MHz.

Specialized Feature Summary

• Provides high-performance I/O expansion and switching between upstream and downstream ports
• Supports root-to-peripheral and peer-to-peer data transfers
• Includes internal buffering and flow control credits for large payloads

Specialized Applications

• PCIe system interconnect switching
• I/O expansion in server architectures
• High-performance peripheral connectivity

Specialized Procurement Notes

Verify the exact suffix against official documentation, as variations exist. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check for moisture sensitivity handling requirements due to the BGA package type. Ensure compatibility with existing PCB layouts before procurement.

Specialized Selection Notes

Select this component when 24 lanes and three ports are required for PCIe Gen2 applications. Compare against the 89HPES24T3G2ZCAL8 if a smaller 324-pin package is preferred. Verify thermal management capabilities for the 676-pin FCBGA form factor. Ensure the design supports the specified voltage rails and operating temperature range.

Specialized Part Context

This part belongs to the IDT/Renesas PRECISE family of PCIe switches. It shares architectural similarities with other models like the 89HPES24N3A1ZCBX8 but differs in pin count and package size. The 676-pin variant offers specific layout advantages over the 324-pin versions found in similar lane-count devices.

Specialized Replacement Considerations

The 89HPES24T3G2ZCAL8 is a related model but uses a 324-pin FCBGA package. Direct replacement requires re-evaluation of the PCB footprint and routing. Verify electrical compatibility and pin mapping differences before substitution.
