The Realtek RTL8152 is a USB-to-Ethernet controller chip that allows devices to connect to a wired Ethernet network via a USB port. It is commonly used in compact devices such as laptops, tablets, and mini-PCs that do not have a built-in Ethernet port.
The RTL8152 supports 10/100 Mbps Ethernet and is compatible with USB 2.0 interfaces. It uses a low-power design to minimize power consumption, making it suitable for use in portable devices. The chip is also equipped with advanced power management features, such as Wake-on-LAN, which allows devices to be remotely powered on from a sleep or standby state.
