MARVELL 88E6020-B1-NNC2I000: A Robust 5-Port Fast Ethernet Switch Controller for Embedded Networking
The MARVELL 88E6020-B1-NNC2I000 stands as a highly integrated, low-power, and feature-rich 5-port Fast Ethernet switch controller, designed to meet the demanding requirements of modern embedded networking applications. This system-on-chip (SoC) solution is engineered to provide a complete Layer 2 switching fabric, making it an ideal cornerstone for a wide array of devices including industrial control systems, IP cameras, network-attached storage (NAS), and small office/home office (SOHO) networking equipment.
At its core, the device incorporates five integrated 10/100 Mbps Ethernet PHYs, eliminating the need for external physical layer transceivers and significantly reducing the total bill of materials (BOM) and board space. This high level of integration is a key driver for cost-effective and compact designs. The switch supports full-wire speed, non-blocking switching across all ports, ensuring that data flows efficiently without internal bottlenecks, which is critical for maintaining network performance and low latency.
A standout feature of the 88E6020 is its sophisticated Quality of Service (QoS) support. It employs a priority-based scheduling mechanism with four queues per port, allowing network traffic to be classified and prioritized effectively. This ensures that delay-sensitive data, such as voice or video streams, is forwarded ahead of less critical traffic, enhancing the overall user experience in converged networks.
The controller also boasts advanced security and management capabilities. It supports IEEE 802.1Q VLAN tagging for logical network segmentation and security, and IGMP snooping for optimized multicast traffic management, preventing unnecessary flooding of multicast data to all ports. For network management and diagnostics, it offers SNMP (Simple Network Management Protocol) support and comprehensive MIB (Management Information Base) counters, providing deep visibility into network performance and health.
Furthermore, the Marvell 88E6020 is built for robustness and ease of implementation. It operates with a single 3.3V power supply and is housed in a compact 128-pin LQFP package, suitable for space-constrained environments. Its low power consumption makes it an excellent choice for energy-conscious applications.
ICGOOODFIND: The Marvell 88E6020-B1-NNC2I000 is a proven and highly integrated solution that delivers a complete, managed Fast Ethernet switching platform. Its blend of high integration, robust Layer 2 features, and advanced traffic management makes it a versatile and reliable choice for developers building the next generation of connected embedded systems.
