89HPES24T3G2ZEALG

Specialized Overview

The 89HPES24T3G2ZEALG is a PCI interface IC manufactured by Renesas Electronics, belonging to the PRECISE series. 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 optimized for maximum bandwidth and large payloads. It operates at a supply voltage of 3.3V and utilizes a 324-FCBGA package (19x19 mm). This component provides low latency and low power consumption suitable for system interconnect applications.

Specialized Feature Summary

• Provides high-performance I/O expansion and switching functions between an upstream port and downstream ports.
• Supports non-blocking throughput for multiple traffic flows regardless of switch loading.
• Features internal buffering and flow control credits optimized for maximum bandwidth and large payloads.

Specialized Applications

• PCI Express system interconnect switching
• High-performance I/O expansion systems
• Root-to-peripheral data transfer architectures

Specialized Procurement Notes

Verify the exact suffix 'ZEALG' against official Renesas documentation, as standard listings often use 'ZCAL8'. Confirm moisture sensitivity level and RoHS compliance status directly from the manufacturer datasheet before procurement planning.

Specialized Selection Notes

Select this component when a 3-port, 24-lane PCIe Gen2 switch is required for deterministic system interconnect. Ensure the design accommodates the 324-FCBGA footprint and 3.3V power requirements. Verify compatibility with existing PCIe controller logic for proper lane mapping.

Specialized Part Context

This part belongs to the IDT/Renesas PRECISE family of PCIe switches. It shares architectural similarities with models like the 89HPES24T3G2ZCAL8 but differs in packaging or environmental specifications defined by the specific suffix. It serves as a bridge for expanding PCIe connectivity in server and storage environments.

Specialized Replacement Considerations

Direct substitutes include the 89HPES24T3G2ZCAL8 and 89HPES24T3G2ZCALGI. Verify pinout and electrical characteristics match before substitution, as suffix variations may indicate different temperature grades or packaging types.
