Overview
The 89HPES8T5ZHBCGI is a PCI Express switch component manufactured by Renesas Electronics Corporation. It functions as an interface IC designed to provide high-performance I/O expansion and switching capabilities within system architectures. The device facilitates data transfer between PCIe upstream ports and downstream ports, supporting both root-to-peripheral and peer-to-peer communication modes. This specific part number represents the integrated switch controller, distinct from evaluation kits or development boards associated with the PES series.
Feature Summary
- Provides high-performance I/O expansion and switching functions between a PCIe upstream port and downstream ports
- Supports peer-to-peer switching between downstream ports for flexible system interconnect topologies
Applications
- PCIe I/O expansion systems requiring non-blocking throughput
- Server and workstation architectures utilizing peer-to-peer data transfers
- System designs needing low latency and low power consumption for switch operations
Procurement Notes
Verify the exact ordering suffix against current manufacturer documentation to confirm package type and temperature grade. Confirm availability status as legacy components may have limited supply or end-of-life notifications. Ensure compatibility with existing PCB footprints and design rules before procurement.
Selection Notes
Select this component when designing systems that require dedicated hardware switching for PCIe lanes rather than software-based routing. Compare against other PES series variants based on the required number of downstream ports and specific performance metrics such as payload size support and internal buffering requirements.
Part Context
This part belongs to the IDT/PES family of PCI Express switches developed by Integrated Device Technology, now part of Renesas Electronics. These devices are engineered to bridge host processors with peripheral devices, offering deterministic switching performance essential for high-bandwidth applications in enterprise and industrial environments.
Replacement Considerations
Consult official Renesas cross-reference documents for verified substitute part numbers. Consider newer generations of PCIe switches if the original component is discontinued. Verify pinout and register compatibility before substituting with similar interface ICs.
