8.10. Ethernet
The LAN9221 Ethernet controller is wired on the FSM bus and uses the chip-select FSMC_CS0n.
Figure 8.16 illustrates the circuitry that applies to the Ethernet interface on the board.
Figure 8.16. Ethernet 10/100
The LAN9221i is a full-featured, single-chip 10/100 Ethernet controller designed for embedded
applications where performance, flexibility, ease of integration and system cost control are required.
The LAN9221/LAN9221i has been specifically designed to provide high performance and throughput
for 16-bit applications. The LAN9221/LAN9221i is fully IEEE 802.3 10BASE-T and 802.3u
100BASE-TX compliant, and supports HP Auto-MDIX. The variable voltage I/O signals of the
LAN9221/LAN9221i accommodate lower voltage I/O signalling without the need for voltage level
shifters.An EEPROM wired to the LAN9221i is available on the Snowball board to store the MAC
address.
