BCM5325FKQMG

Overview

The BCM5325FKQMG is a five-port 10/100 Ethernet switch integrated circuit manufactured by Broadcom. It features an on-chip packet buffer to manage data flow across the five Fast Ethernet ports. The device supports standard IEEE 802.3 and 802.3u protocols for reliable network communication. It is designed for low pin count applications, reducing external component requirements. The chip integrates MAC functions with switching capabilities, suitable for cost-sensitive networking solutions.

Feature Summary

• Integrates five 10/100 Mbps Ethernet ports with built-in packet buffering
• Supports full-duplex and half-duplex operation modes
• Includes hardware-based flow control mechanisms

Applications

• Five-port desktop switches
• Industrial Ethernet gateways
• Network interface expansion modules

Procurement Notes

Verify the specific suffix KQMG against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with existing PCB footprints before ordering. Check for RoHS compliance status in the latest documentation.

Selection Notes

Select this component when a fixed five-port Fast Ethernet solution is required without external PHYs. Compare port density and power consumption against similar Broadcom models like the BCM5325M if higher integration is needed. Evaluate board space constraints due to the QMG package.

Part Context

This part belongs to the Broadcom BCM5325 family of non-managed Ethernet switches. It shares core architecture with variants like the BCM5325MA2KQMG but differs in packaging or environmental specifications. It serves as a foundational component for simple Layer 2 switching applications.

Replacement Considerations

The BCM5325M and BCM5325MA2KQMG are functionally similar five-port switches. Verify pinout compatibility and thermal characteristics before substituting. Ensure the alternative meets the same voltage and protocol standards.
