PM40036B1-F3EI

Overview

The PM40036B1-F3EI is a member of the Switchtec PFX Gen 4 Fanout PCIe Switch Family, manufactured by Microchip Technology. This device provides 36 lanes and supports up to 20 ports with 18 non-transparent bridges (NTBs) and 10 virtual switch partitions. It features hot- and surprise-plug controllers for each port and advanced error containment mechanisms including AER and DPC. The switch operates at PCIe Gen 4 speeds of 16 GT/s and includes an integrated MIPS processor for management tasks.

Feature Summary

• Supports logical non-transparent interconnect allowing for larger topologies
• Includes high-performance ultra-low latency DMA engine
• Provides comprehensive diagnostics with real-time eye capture and external loopback capability

Applications

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

Procurement Notes

Verify the exact part number suffix against official documentation, as variations exist within the family. Confirm package type and temperature grade requirements before ordering. Ensure compatibility with existing system firmware and BIOS configurations. Check for specific evaluation kit availability if hardware validation is required during development phases.

Selection Notes

Select this model when 36 lanes and 20 ports are sufficient for the target topology. Consider higher lane counts like the PM40100 or PM40052 if more bandwidth or partitioning is needed. Evaluate the need for specific I/O interfaces such as Ethernet MAC or SGPIO based on peripheral connectivity requirements.

Part Context

This component belongs to the Switchtec PFX Gen 4 Fanout PCIe Switch Family, which also includes variants with 28, 52, 68, 84, and 100 lanes. All family members share similar core architectures, error handling capabilities, and diagnostic tools, differing primarily in lane count, port density, and partition limits.

Replacement Considerations

Direct replacements within the same family include PM40028B-F3EI for lower capacity needs or PM40052B-F3EI for higher capacity. Cross-family migration requires re-evaluation of pinout compatibility and software support.
