89HPES24T3G2ZCBLG8

Overview

The 89HPES24T3G2ZCBLG8 is a PCI Express interface integrated circuit manufactured by Renesas Electronics. It functions as a 24-lane, 3-port Gen2 PCIe switch designed 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 to optimize bandwidth and handle large payloads. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 676-pin FCBGA package measuring 27x27 mm with a 1 mm pitch. The component requires 3.3V power supply and is classified as a specialized switch interface IC.

Feature Summary

• Provides high-performance I/O expansion and switching between upstream and downstream ports
• Supports non-blocking throughput for multiple traffic flows regardless of switch loading
• Optimized for maximum bandwidth and large payload sizes through internal buffering

Applications

• PCIe system interconnect switching
• I/O expansion in server architectures
• Peer-to-peer data transfer applications

Procurement Notes

Verify the specific suffix 'ZCBLG8' against official Renesas documentation to confirm pinout and packaging details, as generic family listings may omit these distinctions. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) that may affect long-term availability or manufacturing changes.

Selection Notes

Select this component when a 3-port, 24-lane PCIe Gen2 switch architecture is required for deterministic system interconnect. Ensure the design accommodates the 676-lead FCBGA footprint and thermal dissipation needs. Verify that the 3.3V power domain aligns with the system's voltage rails and that the industrial temperature grade meets environmental specifications.

Part Context

This part belongs to the 89HPES24T3G2 series of PCIe switches from Renesas Electronics. It is distinct from other variants in the family based on its specific package type and lead-free status indicated by the suffix. The series is generally used for high-bandwidth switching applications requiring low latency and efficient flow control mechanisms.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic cross-references are not recommended due to potential differences in pin configurations and electrical characteristics.
