PM50036B1-FEI

Overview

The PM50036B1-FEI is a Switchtec PFX Gen 5 Fanout PCIe switch manufactured by Microchip Technology. It supports 36 lanes and provides 10 logical non-transparent partitions with 20 hot-plug controllers per port. The device operates at PCIe Gen 5 speeds of 32 GT/s and includes an integrated MIPS processor for management functions.

Feature Summary

• Supports up to 48 nontransparent bridges assignable to any port
• Includes high-performance, ultra-low latency cut-through DMA engine with up to 64 channels
• Features advanced error containment mechanisms including AER and DPC on all ports

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with required firmware versions before integration into system designs.

Selection Notes

Select this model when 36 lanes are sufficient for the topology. Consider higher lane counts like the PM50052 or PM50100 if more bandwidth is needed. Verify partition requirements align with the 10 available logical NT interconnects.

Part Context

This component belongs to the Switchtec PFX/PSX Gen 5 Fanout PCIe Switch Family. It shares architectural features with other family members such as the PM50100 and PM50052, differing primarily in lane count and partition capacity.

Replacement Considerations

Direct substitutes within the same family include the PM50052B1-FEI and PM50028B1-FEI. Verify pinout and software configuration compatibility when migrating between different lane counts.
