89HPES24T3G2ZBAL

Specialized Overview

The 89HPES24T3G2ZBAL 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 with internal buffering and flow control credits optimized for large payloads. It operates on a 3.3V supply voltage and utilizes a 324-FCBGA package (19x19 mm). This component provides low latency and low power consumption for system interconnect switching applications.

Specialized Feature Summary

• Switch architecture optimized for I/O expansion supporting root-to-peripheral and peer-to-peer data transfers
• Internal buffering and flow control credits optimized for maximum bandwidth and large payloads
• Low latency and low power consumption design

Specialized Applications

• PCI Express system interconnect switching
• High-performance I/O expansion
• Root-to-peripheral data transfer routing

Specialized Procurement Notes

Verify the exact suffix 'ZBAL' against official Renesas documentation, as public records primarily list variants such as ZCAL8 or ZCBX8. Confirm moisture sensitivity level and lead-free status prior to procurement. Ensure compatibility with the 324-FCBGA footprint and 3.3V operating requirements during integration planning.

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 models like the 89HPES24N3A1ZCBX8 if Gen1 support suffices. Verify that the 324-FCBGA package size fits the target PCB layout constraints.

Specialized Part Context

This part belongs to the Renesas PRECISE series of PCIe switches. It shares architectural similarities with other models in the 89HPES24 family, such as the 89HPES24T3G2, which offers comparable lane counts and port configurations. These devices are engineered for deterministic system interconnect switching with non-blocking throughput capabilities.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers for the specific ZBAL suffix variant are not available in the provided source material. Consider evaluating the 89HPES24T3G2ZCAL8 or 89HPES24N3A1ZCBX8 for functional equivalence, pending verification of pinout and electrical parameter compatibility.
