Optional 1-Wire EEPROM
The SAMA5D3 Xplained board can use a 1-Wire device as “soft label” to store data such as chip type,
manufacturer’s name, production date, etc.

10/100/100 Ethernet Port
The SAMA5D3 Xplained board features a MICREL PHY device (KSZ9031RN) operating at 10/100/1000 Mb/s. The
board supports the RGMII interface mode. The Ethernet interface consists of four pairs of low-voltage differential
pair signals designated from GRX± and GTX± plus control signals for link activity indicators. These signals are
routed to the 10/100/1000 BaseT RJ45 connector (J12).
For monitoring and control purposes, LEDs are integrated in the RJ45 connectors to indicate activity, link, and
speed status information for the corresponding ports.
For more information about the Ethernet controller device, refer to the MICREL KSZ9031RN datasheet.
