89HPES24T3G2ZBALG8

Specialized Overview

The 89HPES24T3G2ZBALG8 is a PCI interface IC manufactured by Renesas Electronics, belonging to the PRECISE series. It functions as a 24-lane, 3-port Gen2 PCIe switch designed for high-performance I/O expansion. The device supports root-to-peripheral and peer-to-peer data transfers within a non-blocking architecture. It utilizes a 324-FCBGA package with dimensions of 19x19 mm. The component operates on a 3.3V supply voltage and is rated for commercial temperature grades. It features internal buffering and flow control credits optimized for maximum bandwidth and large payloads.

Specialized Feature Summary

• Provides high-performance I/O expansion and switching between one upstream port and two downstream ports.
• Supports peer-to-peer switching capabilities between downstream ports.
• Features internal buffering and flow control credits optimized for maximum bandwidth and large payloads.

Specialized Applications

• PCI Express system interconnect switching
• High-performance I/O expansion in computing systems
• Root-to-peripheral data transfer architectures

Specialized Procurement Notes

Verify the exact suffix 'ZBALG8' against official Renesas documentation, as public records predominantly list 'ZCAL8' or 'ZCALGI' variants for this model family. Confirm RoHS compliance status and moisture sensitivity levels directly from the manufacturer datasheet before procurement planning. Ensure compatibility with existing PCB footprints for the 324-FCBGA package.

Specialized Selection Notes

Select this component when a 3-port PCIe Gen2 switch with 24 lanes is required for I/O expansion. Compare against other PRECISE series switches like the 89H24NT6AG2 if higher port counts are needed. Verify that the 324-FCBGA package size fits the design constraints. Ensure the application requires Gen2 speeds and does not necessitate Gen3 retimers.

Specialized Part Context

This part belongs to the IDT/Renesas PRECISE PCIe Switch family, which focuses on deterministic system interconnect solutions. These switches are engineered for low latency and low power consumption. The 89HPES24T3G2 series specifically targets applications requiring efficient routing between upstream hosts and multiple peripheral devices without blocking throughput.

Specialized Replacement Considerations

Publicly available substitute part numbers for the specific ZBALG8 suffix are not confirmed in standard distributor catalogs. Consider verifying cross-reference availability through Renesas engineering support. Alternative PRECISE series switches may require schematic and layout modifications due to pinout differences.
