Microchip's LAN9354/LAN9354i is a high-performance, small-footprint, full-featured 3-port managed Ethernet switch. This device is application-optimized for consumer, embedded and Industrial electronic designs which require a highly integrated, cost effective device with switching functionality, flexibility and ease of integration. 

Featuring a small form factor, the LAN9354/9354i supports compact PCB. The virtual PHY feature mimics a single PHY connection through the RMII interface to the host SoC, which can reduce software development time. This feature also allows system designers to swap the and Ethernet switch with a single PHY to create multiple products from the same software driver. 

IEEE1588v2 is supported via an integrated hardware time stamp unit, which supports end-to-end and peer-to-peer transparent clocks. The LAN9354 complies with the IEEE 802.3 (full/half-duplex 10BASE-T and 100BASE-TX) Ethernet protocol, IEEE 802.3az Energy Efficient Ethernet (EEE) (100Mbps only), and 802.1D/802.1Q network management protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications. 100BASE-FX is supported via an external fiber transceiver (SFP and SFF Physical medium).
