MARVELL 88E3082-C1-BAR1C000 Ethernet Switch Controller Datasheet and Technical Overview

The MARVELL 88E3082-C1-BAR1C000 is a highly integrated, low-power, and high-performance 8-port Gigabit Ethernet switch controller designed for a wide array of enterprise, industrial, and embedded networking applications. This system-on-chip (SoC) combines a robust switching fabric with advanced management features, offering a compact and efficient solution for modern network infrastructure.

Architecture and Core Features

At its heart, the 88E3082 features an 8-port Gigabit Ethernet switch with an integrated high-speed serial interface for uplink connectivity. It is built around a sophisticated packet processing engine that supports non-blocking, wire-speed switching on all ports simultaneously. The controller incorporates a high-performance CPU complex for advanced management and configuration, allowing for flexible control plane processing.

A key architectural highlight is its support for Quality of Service (QoS) features, including priority queues, traffic shaping, and classification based on IEEE 802.1p, DSCP, and other layer 2/3/4 fields. This ensures optimal handling of latency-sensitive traffic like voice and video. Furthermore, it provides robust Security and Access Control List (ACL) capabilities, enabling network administrators to enforce policies and mitigate unauthorized access.

Advanced Switching Capabilities

The device supports a comprehensive set of Layer 2 switching protocols, including IEEE 802.1Q VLAN for network segmentation, IGMP snooping for efficient multicast traffic management, and Spanning Tree Protocol (STP/RSTP/MSTP) for network loop prevention and redundancy. These features make it suitable for building resilient and manageable network topologies.

Energy Efficiency

Marvell has placed a strong emphasis on power conservation with this controller. It supports Energy Efficient Ethernet (EEE) as defined by the IEEE 802.3az standard. This technology allows the PHYs to enter a low-power idle state during periods of low data activity, significantly reducing overall power consumption without affecting performance.

Target Applications

The integration and feature set of the 88E3082 make it ideal for a diverse range of applications:

Managed Network Switches: For small to medium-sized business (SMB) and enterprise workgroup switching.

Industrial Networking: Ruggedized designs for automation and control systems.

Embedded Systems: Network connectivity in printers, storage systems, and security appliances.

IP Surveillance: Building blocks for Network Video Recorders (NVRs) and video storage systems.
