4.2.3 Ethernet
The ATSAM4E16E has a built in 10/100 Mbps Ethernet IEEE
®
802.3 MAC with an MII interface. SAM4E
Xplained Pro connects the MAC to a Micrel KSZ8081MNXIA physical-layer transceiver which is connected to
one RJ45 Ethernet connector.
Every SAM4E Xplained Pro kit is assigned a unique MAC48 address that can be used in an application, this
address is printed on the label on the bottom side of the kit and stored in the EDBG. For more information see
“Hardware Revision History and Known Issues” on page 21 and “Kit Specific Data” on page 20.
Table 4-8, “RJ45 Connections” on page 16 lists all I/O-lines connected to the Ethernet PHY.
