Overview
The 89HPES34H16ZABLHI is a high-performance PCIe Gen3 system interconnect switch manufactured by Renesas Electronics. It provides 64 PCIe Gen3 lanes and 16 switch ports, delivering non-blocking throughput for multiple traffic flows regardless of switch loading. The device features a partitionable architecture supporting true multi-root configurations. It operates on a 3.3V supply voltage and utilizes a 288-LBGA package with dimensions suitable for surface mount installation.
Feature Summary
- Provides deterministic system interconnect switching with full line rate, non-blocking throughput across all ports.
- Features a partitionable switch architecture designed to support true multi-root configurations.
- Includes internal buffering and flow control credits optimized for maximum bandwidth and large payloads.
Applications
- High-performance computing systems requiring scalable I/O expansion
- Storage area networks needing low-latency data transfer
- Telecommunications infrastructure demanding reliable signal integrity
Procurement Notes
Verify the specific ordering suffix against official Renesas documentation to ensure correct package type, temperature grade, and lead-free status. Confirm current product lifecycle status as older variants may be obsolete. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a high-density PCIe Gen3 switch with 16 ports is required. Ensure the design supports the necessary 3.3V power domain and thermal dissipation for the LBGA package. Verify that the application benefits from partitionable multi-root capabilities and non-blocking switching performance.
Part Context
This part belongs to the PRECISE series of PCIe switches from Renesas. It complements other models in the family by offering Gen3 speeds and a 16-port configuration, distinct from lower-lane or Gen2 variants. It serves as a critical node for expanding PCIe connectivity in complex server and storage architectures.
Replacement Considerations
Direct replacements must match the 64-lane, 16-port Gen3 specification. Check for updated suffixes indicating revised packaging or environmental compliance. Verify pin-to-pin compatibility if substituting within the same Renesas family.
