Microchip‘s LAN9303/LAN9303i is a high-performance， small-footprint， full-featured 3-port managed Ethernet switch. This device is application-optimized for consumer， and embedded electronics designs which have a rapid development cycle and require low-cost switching functionality， flexibility and ease of integration.
Featuring the industry’s smallest form factor 3-port switch， the LAN9303/9303i supports compact PCB design and MII/RMII/Turbo MII （Media Independent， Reduced Media Independent and Turbo Media Independent Interfaces）。 This device supports Turbo MII mode to accomplish network speeds up to 200 Mbps. The virtual PHY feature mimics a single PHY connection through the MII/RMII/Turbo MII interface to the host SoC， which can reduce software development time. This feature also allows system designers to swap the single PHY and Ethernet switch to create multiple SKUs from the same software driver. Additionally， the LAN9303/9303M offer the industry‘s highest （±8kV/15kV） per-port ESD protection.
The LAN9303/9303i switch combines all of the functions of a 10/100 system， including the switch fabric， packet buffers， buffer management， MACs， PHY transceivers and optional serial management functions. Both devices comply with IEEE 802.3 10BASE-T and 100BASE-TX Ethernet protocol specifications， enabling compatibility with industry standard Ethernet and Fast Ethernet applications.
