Due to the high bandwidth and long cable length requirements, Ethernet applications can utilize a significant amount of power. ENC424J600/624J600 devices include power-down and PHY power management features to assist low-power applications. While features cannot completely mitigate power requirements, they can help reduce power consumption when the Ethernet interface is not needed.
