Procurement Notes
This component is officially listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life notices. Engineering change notices or product discontinuation notifications should be reviewed prior to procurement planning to ensure supply chain stability for existing designs.
Selection Notes
Designers requiring this specific 16-lane, 7-port configuration must account for its discontinued status. Alternative selection should focus on newer members of the PRECISE family or compatible PCIe switches from Renesas that offer updated support and availability. Verify pinout and electrical compatibility if substituting with similar models in the 89HPES series.
Part Context
The 89HPES16T7ZHBXI is part of the 89HPES16T7 series, which features a 16-lane, 7-port PCIe I/O expansion switch architecture. This series is engineered to support both root-to-peripheral and peer-to-peer data transfers, utilizing internal buffering and flow control credits to optimize bandwidth and handle large payloads efficiently.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation due to the component's discontinued status. Users should consult Renesas official resources for recommended replacements within the PRECISE family.
