¡¡¡¡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 £¨¡À8kV/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.
