VSC7512
10-Port Layer-2 Gigabit Ethernet Switch
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.
