The LAN9303M is a full featured, three-port 10/100 managed Ethernet switch designed for embedded
applications where performance, flexibility, ease of integration and system cost control are required.
The LAN9303M combines all the functions of a 10/100 Ethernet switch system, including the Switch
Fabric, packet buffers, Buffer Manger, MACs, PHY transceivers, and serial management. The
LAN9303M complies with the IEEE 802.3 (full/half-duplex 10BASE-T and 100BASE-TX) Ethernet
protocol specification and 802.1D/802.1Q management protocol specifications, enabling compatibility
with industry standard Ethernet and Fast Ethernet applications.
The EVB9303M is an Evaluation Board (EVB) that utilizes the LAN9303M to provide a fully functional
three-port dual MII/RMII/Turbo MII Ethernet switch. The EVB9303M provides two fully integrated
MAC/PHY Ethernet ports (Ports 1 & 2) via on-board RJ45 connectors. Port 0 and Port 1 each provide
two MII port connectors (for a total of 4) which support the following:
The Port 0 and Port 1 modes of operation are configured via a single, 8-position, mode-configuration
strap switch.
Power is supplied to the board via a +5V external wall-mount power supply. The external supply is not
necessary when Port 0 or Port 1 is configured for (and used in) PHY mode. In such cases, the +5V
power rail is typically supplied through the MII connector from the MAC side.
The EVB9303M includes a 8Kx8 I
settings from the EEPROM into the device at reset, allowing the device to operate unmanaged. An I
host adapter interface header (10-pin, 2x5) is provided to simplify I
