SERIAL ETHERNET ON BOARD
Ethernet is the most common Local Area Network (LAN) technology in use today. On the
top of the physical layer Ethernet stations mutually communicate by sending data packets to
each other. Each Ethernet station is given a single 48-bit MAC address which is used to
specify both the destination and the source of each data packet.
Serial Ethernet has 28-pin ENC28J60 10BASE-T Ethernet Controller with on-board Media
Access Control and Physical Layer (MAC &PHY), 8 Kbytes of Buffer RAM and Serial
Peripheral Interface (SPI) communication.

Serial Ethernet
Note:
Make sure to select proper voltage level depending on MCU Card attached to your
UNI-DS3 development board.
Improper voltage level can damage development system or Serial Ethernet!
Switches 7 and 8 on SW2 as well as switches 1 and 2 on SW3 have to be turned on to enable
Serial Ethernet. Switches 4, 5 and 6 on SW4 have to be turned on to enable SPI communi-
cation, Fig. 37.
