PM8565B-FEI

Specialized Overview

The PM8565B-FEI is a PCIe switch integrated circuit manufactured by Microchip Technology, belonging to the Switchtec PFX-L series. It supports PCIe Gen3 x16 topology with 80 lanes and 40 ports. The device operates within a temperature range of -40°C to +105°C and utilizes a BBGA-1311 surface-mount package. Standard interfaces include 2-Wire, GPIO, JTAG, and UART for configuration and management.

Specialized Feature Summary

• Supports high-density PCIe Gen3 connectivity with 80 lanes and 40 ports
• Integrated hardware-based security features including secure boot and encrypted firmware updates
• Advanced traffic management capabilities with Quality of Service (QoS) and bandwidth allocation
• Comprehensive system management via standard interfaces like JTAG and UART

Specialized Applications

• High-performance computing servers requiring extensive I/O expansion
• Data center infrastructure with dense storage and networking requirements
• Enterprise networking equipment needing scalable PCIe fabric architectures

Specialized Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and check for recent Product Change Notifications (PCNs) regarding packaging or material updates. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Specialized Selection Notes

Select this model when 80 lanes of PCIe Gen3 connectivity are required in a compact form factor. Compare against the PM8534B-FEI if fewer lanes suffice, or consider encryption-enabled variants if security features are mandatory. Verify thermal design adequacy for the BBGA-1311 package in the target application environment.

Specialized Part Context

This component is part of Microchip's Switchtec family of PCIe switches, designed for enterprise and data center applications. It complements other models like the PM8535B-FEI, offering specific lane counts and port configurations tailored to different scalability needs within PCIe fabric architectures.

Specialized Replacement Considerations

Direct substitutes may include PM8535B-FEI for similar functionality with different lane counts. Cross-reference datasheets for pin compatibility and electrical specifications before substitution.
