PM8536B-FEI

Specialized Overview

The PM8536B-FEI is a Switchtec Gen 3 PCIe switch manufactured by Microchip Technology. It features 96 lanes and 48 ports, designed for high-performance data center interconnects. The device operates within a temperature range of -40°C to +105°C and utilizes an FCBGA-1311 package for surface mount installation. Supported interfaces include 2-Wire, GPIO, JTAG, and UART for configuration and control. This component belongs to the PCI interface IC category and is classified as a Switch - PCIe type.

Specialized Feature Summary

• Supports PCIe Gen 3 standard with 96 lanes and 48 ports for scalable connectivity
• Includes management interfaces such as JTAG, UART, GPIO, and 2-Wire for system integration
• Designed for industrial operating temperatures ranging from -40°C to +105°C

Specialized Applications

• Data center server interconnects
• Storage area network (SAN) switches
• High-performance computing clusters

Specialized Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct package and temperature grade. Confirm RoHS compliance status through current datasheets or environmental reports before procurement. Check for any recent Product Change Notifications (PCN) regarding packaging or material updates. Ensure compatibility with existing board design constraints for the FCBGA-1311 footprint.

Specialized Selection Notes

Select this model when 96 lanes and 48 ports are required for PCIe Gen 3 architectures. Compare against PM8535B-FEI for 80-lane configurations or PM8534B-FEI for 64-lane requirements if lower port counts suffice. Verify that the FCBGA-1311 package fits the target PCB layout. Ensure thermal management solutions support the operational environment up to +105°C.

Specialized Part Context

This part belongs to the Microchip Switchtec family of PCIe switches. It complements other models like PM8535B-FEI and PM8534B-FEI, offering varying lane counts. The PM8536B-FEI specifically targets applications needing maximum port density in the Gen 3 series. It shares interface similarities with other Switchtec devices but differs in physical lane count and port architecture.

Specialized Replacement Considerations

PM8536A-FEIP is a previous prototype version with identical 96-lane/48-port specifications but may differ in silicon revision or availability status. Direct pin-to-pin replacements within the same family include PM8535B-FEI (80 lanes) and PM8534B-FEI (64 lanes), though these offer reduced capacity.
