89HPES32T8ZHBXI

Overview

The 89HPES32T8ZHBXI is a PCIe I/O expansion switch manufactured by Renesas Electronics. It provides 32 PCIe Gen1 lanes across 8 ports, operating at a maximum clock frequency of 125 MHz with a data rate of 256 Gb/s. The device supports power supply voltages of 1 V, 2.5 V, and 3.3 V. It operates within a temperature range of -40°C to +85°C and utilizes an FCBGA-484 surface-mount package.

Feature Summary

• Switch architecture optimized for I/O expansion applications
• Supports root-to-peripheral and peer-to-peer data transfers
• Internal buffering and flow control credits optimized for large payloads

Applications

• PCIe I/O expansion systems
• Root-to-peripheral switching
• Peer-to-peer downstream switching

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as documentation may indicate non-compliance. Validate the specific suffix ZHBXI against official datasheets to ensure correct temperature grade and packaging specifications before procurement.

Selection Notes

Select this component for designs requiring high-performance I/O expansion rather than system interconnect. Ensure the design accommodates the FCBGA-484 package requirements. Verify that the application utilizes PCIe Gen1 lanes, as this model does not support Gen2 speeds found in other family members.

Part Context

This part belongs to the 89HPES32T8G2 series, which focuses on I/O expansion functions. It differs from the 89HPES32H8 series, which is designed for high-performance system interconnect with partitionable architectures. The 89HPES32T8 series prioritizes low latency and power efficiency for peripheral connectivity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the 89HPES32T8ZAAL or similar variants within the same series if pin compatibility and electrical characteristics match the original design requirements.
