PM40036B-F3EI

Overview

The PM40036B-F3EI is a Switchtec PFX Gen 4 Fanout PCIe switch supporting 36 lanes and 20 ports with 18 non-transparent bridges. It features up to 10 virtual switch partitions and hot-plug controllers for each port. The device operates at PCIe Gen 4 speeds of 16 GT/s and includes an integrated MIPS processor. It supports passive, managed, and optical cables via SFF-8644, SFF-8643, SFF-8639, and OCuLink connectors. Peripheral interfaces include up to 11 Two-Wire Interfaces, 4 SGPIO ports, 4 UARTs, JTAG, and a 10/100 Ethernet MAC.

Feature Summary

• High-performance non-blocking architecture with logical non-transparent interconnect capabilities
• Advanced error containment including AER, DPC, and Completion Timeout Synthesis
• Comprehensive diagnostics with real-time eye capture and external loopback
• Flexible port bifurcation supporting x1, x2, x4, x8, and x16 configurations

Applications

• Data center equipment
• Defense and industrial servers
• Cellular infrastructure
• Metro networks and core networking

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with required firmware versions and evaluation tools like the ChipLink Diagnostic Tools for proper system integration and validation.

Selection Notes

Select this model for designs requiring 36 lanes and 20 ports within the PFX family. Consider variants with higher lane counts if additional throughput or partitioning is needed. Verify support for required cable types and connector standards during the design phase.

Part Context

This component belongs to the Switchtec PFX Gen 4 Fanout PCIe Switch Family, which also includes models PM40100, PM40084, PM40068, PM40052, and PM40028. These devices share common architectural features such as high-reliability PCIe support and advanced error containment mechanisms.

Replacement Considerations

Direct replacements within the same family include PM40052B-F3EI (52 lanes) or PM40028B-F3EI (28 lanes). Verify pinout and firmware compatibility when substituting with different lane counts in the PFX series.
