BCM53282SIPBG

Overview

The BCM53282SIPBG is a network processor integrated circuit manufactured by Broadcom Limited, designed for high-performance networking applications. It features an integrated switch controller with eight Fast Ethernet ports utilizing internal PHYs and two Gigabit Ethernet ports supporting GMII or RGMII interfaces. The device incorporates a MIPS-based processor core to handle complex packet processing tasks. Manufactured in a 176-pin Thin Quad Flat Package (TQFP) with a pitch of 0.5 mm, it operates within a commercial temperature range. The component supports IEEE 802.3 standards for data communication.

Feature Summary

• Integrates an eight-port Fast Ethernet switch controller with built-in physical layer transceivers.
• Provides dual Gigabit Ethernet uplink capabilities via configurable GMII or RGMII interface modes.
• Utilizes an embedded MIPS processor core for advanced packet processing and control plane functions.

Applications

• High-end residential broadband routers
• Enterprise edge routing equipment
• Network access points requiring integrated switching

Procurement Notes

Verify the specific suffix SIPBG against official Broadcom documentation to confirm package type and temperature rating. Ensure compatibility with existing board layouts regarding the 176-pin TQFP footprint. Confirm that the required MIPS core software support is available from the manufacturer or authorized partners before initiating procurement.

Selection Notes

Select this component when a solution combining an eight-port Fast Ethernet switch with dual Gigabit uplinks is required. The integrated PHYs reduce external component count compared to discrete solutions. Verify that the system design can accommodate the thermal requirements of the TQFP package and that the MIPS architecture aligns with the intended firmware development strategy.

Part Context

This part belongs to the Broadcom BCM5328x series of network processors. It serves as a variant within the family, distinguished by its specific packaging and interface configuration. The series is widely utilized in networking infrastructure where integrated switching and processing are necessary to maintain signal integrity and reduce board space.

Replacement Considerations

Consult official Broadcom substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering similar models within the BCM532xx series. Generic replacements may not support the specific MIPS core or interface configurations.
