The Atheros AR8132 PCI-E Fast Ethernet Controller is a network controller chip designed for 10/100 Mbps Ethernet connections. It features a PCI Express interface for integration with computer motherboards. The controller utilizes Atheros' networking technology, including Quality of Service (QoS) and low-power operation. It supports various IEEE 802.3 Ethernet standards, such as 10BASE-T and 100BASE-TX, making it compatible with both Fast Ethernet and Ethernet networks. It employs advanced power management mechanisms, reducing energy consumption in compliance with energy-efficient and eco-friendly design requirements. While not capable of Gigabit Ethernet speeds, it's well-suited for compact and budget-conscious systems where basic wired networking connectivity is essential.
