Marvell 88E6320-A0-NAZ2C000 Ethernet Switch
Marvell 88E6320-A0-NAZ2C000 Product Overview
The 88E6320-A0-NAZ2C000 is a highly integrated 7-port Gigabit Ethernet switch from Marvell's LinkStreet series, designed for enterprise access, SOHO networking, and industrial Ethernet applications. It features 5 integrated 10/100/1000BASE-T PHYs and 2 additional RGMII/MII interfaces for flexible uplink or fiber connectivity, enabling cost-effective and compact network system designs.
The device supports wire-speed layer 2 switching with a non-blocking switch fabric. It operates from a single 3.3 V supply and is housed in a 128-pin QFP package (exposed pad). Operating temperature range is 0 °C to +70 °C. The switch integrates 802.1p QoS, 802.1Q VLAN, IGMP snooping, and link aggregation for robust traffic management. Mass is approximately 1.2 g.

Marvell 88E6320-A0-NAZ2C000 Key Advantages
The 88E6320-A0-NAZ2C000 employs a highly integrated switch architecture, delivering wire-speed layer 2 forwarding while minimizing external component count. The 5 integrated PHYs reduce BOM cost and PCB footprint, while the 2 RGMII/MII interfaces enable flexible connectivity to external Gigabit PHYs, fiber transceivers, or host processors for managed switch designs. The 8K MAC address table and 4K VLANs support medium-sized enterprise networks, while 802.1p QoS with 8 priority queues ensures smooth traffic prioritization for voice and video applications. IGMP snooping optimizes multicast traffic, and link aggregation provides bandwidth scaling and redundancy. The 3.3 V single-supply operation simplifies power design, and the 128-pin QFP package facilitates easy PCB routing and manufacturing.
