PM40052B-F3EI

Overview

The PM40052B-F3EI is a Switchtec PFX Gen 4 Fanout PCIe switch supporting 52 lanes and 28 ports with 14 virtual partitions. It features up to 26 non-transparent bridges, hot- and surprise-plug controllers per port, and advanced error containment including AER and DPC. The device operates at PCIe Gen 4 speeds of 16 GT/s, includes an integrated MIPS processor, and supports ASPM for power management.

Feature Summary

• High-performance non-blocking architecture with flexible lane bifurcation
• Advanced error containment and comprehensive diagnostics capabilities
• Integrated DMA controller and secure boot image authentication

Applications

• Data center equipment
• Defense and industrial servers
• Cellular infrastructure

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with required PCIe Gen 4 link training standards and check for any specific environmental certifications needed for the target deployment environment.

Selection Notes

Select this model when 52 lanes and 28 ports are required within the PFX family. Consider variants like PM40100 or PM40084 if higher lane counts are necessary. Evaluate partition requirements as this unit supports 14 virtual switch partitions compared to other family members.

Part Context

This component belongs to the Switchtec PFX Gen 4 Fanout PCIe Switch Family, which also includes models such as PM40100, PM40084, PM40068, PM40036, and PM40028. These devices share common architectural features but differ in lane count, port density, and partition capacity.

Replacement Considerations

PM40052B-FEI is listed in the datasheet table but lacks explicit F3EI designation details; verify functional equivalence carefully. No direct substitutes are documented.
