PM40100B1-FEI

Overview

The PM40100B1-FEI is a high-reliability PCIe switch from the Switchtec PFX Gen 4 Fanout family, manufactured by Microchip Technology. It supports up to 100 lanes and 52 ports with 26 virtual switch partitions and 48 non-transparent bridges. The device operates at data rates of 16 Gb/s using PCIe Gen 4 technology. It features an integrated MIPS processor, advanced error containment mechanisms including AER and DPC, and comprehensive diagnostics such as real-time eye capture. The component utilizes a BBGA-1467 package for surface mount installation.

Feature Summary

• Supports flexible port bifurcation configurations including x1, x2, x4, x8, and x16 without restrictions on upstream or downstream mapping.
• Integrates advanced error containment capabilities such as Downstream Port Containment (DPC) and Completion Timeout Synthesis (CTS).
• Provides extensive diagnostic tools including real-time eye capture, external loopback, and per-port performance counters.
• Includes peripheral I/O interfaces like Ethernet MAC, UARTs, TWI, and SGPIO for system management.

Applications

• Data center equipment requiring high-density connectivity.
• Defense and industrial servers demanding high reliability.
• Cellular infrastructure and core networking systems.
• Test equipment and video production broadcasting hardware.

Procurement Notes

Verify the specific ordering suffix against official documentation to ensure correct configuration. Confirm compatibility with required host interfaces and power specifications before integration. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this model when maximum lane count and port density are required within the Gen 4 ecosystem. Consider alternative variants like PM40084 or PM40068 if fewer lanes suffice to reduce cost and board space. Ensure the design supports the necessary thermal dissipation for the BBGA-1467 package under full load conditions.

Part Context

This component belongs to the Switchtec PFX Gen 4 Fanout PCIe Switch Family, which includes variants such as PM40084, PM40068, and PM40028. These devices share common architectural features but differ in lane counts and port availability. The PM40100 represents the highest capacity option in this specific generation series.

Replacement Considerations

Direct substitutes include other members of the PFX Gen 4 family such as PM40084B-FEI or PM40068B-FEI, depending on lane requirements. Verify pin-to-pin compatibility and software support for any cross-model replacements.
