PM8043B-F3GI

I/o Expanders Overview

The PM8043B-F3GI is a PCIe switch component manufactured by Microchip Technology, belonging to the Switchtec SXP family. It supports 24 lanes at 12 Gbps data rates. The device is housed in an FBGA-896 package designed for surface mount technology (SMD/SMT). It functions as an I/O expander within the interface IC category. The product status is listed as obsolete or end-of-life.

I/o Expanders Feature Summary

• Supports high-speed serial peripheral interconnect connectivity with 24 lanes operating at 12 Gbps per lane.
• Integrated into the Switchtec SXP series architecture for scalable I/O expansion.
• Designed for robust surface-mount installation in dense electronic assemblies.

I/o Expanders Applications

• High-performance computing systems requiring extensive PCIe connectivity.
• Data center infrastructure utilizing Switchtec-based I/O expansion architectures.
• Enterprise server platforms needing scalable serial interface solutions.

I/o Expanders Procurement Notes

This component is officially classified as obsolete or end-of-life by the manufacturer. Availability is restricted to existing stock or secondary market sources. Buyers should verify the authenticity of the part number and check for Product Change Notifications (PCN) regarding any manufacturing updates before procurement. Due to its discontinued status, long-term supply continuity cannot be guaranteed through standard channels.

I/o Expanders Selection Notes

Engineers replacing this obsolete component must evaluate newer Switchtec generations that offer compatible pinouts or updated performance metrics. Selection should focus on devices supporting similar lane counts and data rates while ensuring package compatibility or designing adapter solutions. Reviewing the latest datasheets for successor models is essential to maintain system integrity and performance standards.

I/o Expanders Part Context

The PM8043B-F3GI represents an earlier generation within Microchip's Switchtec portfolio, specifically tailored for SXP applications. It serves as a bridge for expanding PCIe connectivity in complex server environments. Its designation indicates specific packaging and thermal characteristics distinct from other Switchtec variants like the PM8532 or PM8534 series.

I/o Expanders Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation due to the component's obsolete status. Engineers should consult Microchip for recommended upgrades within the Switchtec Gen 3 or Gen 4 families that match the required 24-lane configuration and FBGA footprint constraints.
