A traditional Ethernet-enabled system (a) is built around an external PHY [physical layer of the open systems interconnection (OSI) model] requiring numerous passives and other components. When the Ethernet PHY is integrated into the MCU (b), board space requirements drop substantially, as do power consumption and system cost
