PM43036B1-F3EI

Overview

The PM43036B1-F3EI is a high-speed connectivity solution designed for in-vehicle networks, functioning as a 36-lane PCIe Gen4 fanout switch. It expands and manages multiple PCI Express connections within high-performance systems. The component is housed in a compact 753-BBGA package, offering significantly higher lane density compared to narrower variants. It supports surface mount installation and utilizes the PFX-A architecture to enhance efficiency and innovation in project development.

Feature Summary

• Provides 36-lane expansion capability for PCI Express Gen4 interfaces
• Utilizes PFX Fanout technology for efficient connection management
• Designed specifically for high-density in-vehicle network applications

Applications

• In-vehicle network connectivity solutions
• High-performance system expansion
• PCIe fanout switching

Procurement Notes

Verify the specific datasheet version and revision history before integration, as Microchip Technology may update pin configurations or electrical characteristics across manufacturing batches. Confirm that the 753-BBGA footprint matches the target PCB design exactly. Ensure compliance with export control regulations associated with this part number prior to international procurement.

Selection Notes

Select this component when a high lane count of 36 is required for PCIe Gen4 signals in space-constrained environments. The BBGA-753 package offers superior density over FBGA options. Consider thermal dissipation requirements inherent to high-speed fanout switches. Validate signal integrity specifications against the specific trace lengths and impedance controls of the target board layout.

Part Context

This part belongs to the PM43036 series of PFX-A fanout switches from Microchip Technology. It is distinct from the PM8043B, which is an I/O expander in an FBGA-896 package. The PM43036B1-F3EI focuses on high-speed serial connectivity rather than general-purpose I/O expansion, serving a different niche within interface ICs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing system architectures before considering alternative vendors or newer revisions within the same product family.
