89HPES24T3G2ZCALG8

Specialized Overview

The 89HPES24T3G2ZCALG8 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 maximum bandwidth and large payloads. It operates at 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

• Provides high-performance I/O expansion and switching functions between a PCIe upstream port and two downstream ports or peer-to-peer switching between downstream ports.
• Supports non-blocking switch architecture optimized for high performance system interconnect with full line rate throughput regardless of switch loading.
• 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
• Root-to-peripheral data transfer systems

Specialized Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm moisture sensitivity level handling requirements during storage and assembly. Check RoHS compliance documentation as indicated in available records. Ensure compatibility with existing PCB layouts using the 324-FCBGA footprint. Validate lead-free specifications against current environmental regulations before procurement.

Specialized Selection Notes

Select this component when requiring a 3-port PCIe Gen2 switch solution with 24 lanes. Consider the 324-FCBGA package size constraints for board design. Evaluate thermal management needs given the surface mount installation type. Compare against newer generations if future-proofing is required, as this model is marked obsolete.
