Overview
The 89HPES32T8ZHBXGI is a PCIe I/O expansion switch manufactured by Renesas Electronics. It provides 32 PCIe Gen1 lanes and 8 switch ports, optimized 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 designed for maximum bandwidth and large payloads. It features low latency and low power consumption. This specific part number is classified as obsolete.
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 architectures.
- Includes internal buffering and flow control credits optimized for maximum bandwidth and large payloads.
Applications
- PCIe I/O expansion systems
- System interconnect switching
- Peripheral connectivity solutions
Procurement Notes
This component is officially listed as obsolete by the manufacturer. Availability is restricted, and it may not be sold in all regions. Verify current stock status with authorized distributors before procurement planning. Consider end-of-life notifications and long-term supply constraints when integrating this part into new designs.
Selection Notes
Select this component only for legacy system maintenance or upgrades where backward compatibility with PCIe Gen1 is required. Evaluate alternative modern switches for new designs due to its obsolete status. Ensure the application benefits from its specific I/O expansion architecture and peer-to-peer capabilities.
Part Context
The 89HPES32T8ZHBXGI belongs to the 89HPES32 series of PCIe switches. It shares functional similarities with other models like the 89HPES32H8 but differs in package and specific interface configurations. It is distinct from the 89KTPES32H8, which is an evaluation kit rather than a standalone switch IC.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, consult Renesas Electronics for recommended modern replacements that offer comparable lane counts and switching performance.
