Description
Microsemi’s industrial Ethernet switch device delivers the industry’s lowest power Gigabit Ethernet (GbE) switching solution. The VSC7512 is a fully-integrated 10-port GbE switch with four copper PHYs in a single package. The VSC7512 leverages Microsemi's SimpliPHY™ technology, resulting in the one of the most cost-effective and lowest power consumption devices in the industry. The single-chip solution utilizes the most advanced Energy Efficient Ethernet features for bringing low-power, high-performance solutions to market. The VSC7512 provides a rich set of unmanaged Ethernet switching features such as Layer-2 forwarding with basic VLAN and QoS processing, enabling the delivery of differentiated services. The VSC7512 contains an 8051 CPU for configuration of the switch. A comprehensive application software package is provided for LED control, loop indication, device overheat protection, and other enhanced functions. Parameters
