The Atheros AR9331 is a highly integrated and cost effective IEEE 802.11n 1×1 2.4 GHz Systemon-a-Chip (SoC) for wireless local area network (WLAN) AP and router platforms. In a single chip, the AR9331 includes a MIPS 24K processor, five-port IEEE 802.3 Fast Ethernet Switch with MAC/PHY, one USB 2.0 MAC/PHY, and external memory interface for serial Flash, SDRAM, DDR1 or DDR2, I2S/SPDIF-Out audio interface, SLIC VOIP/PCM interface, UART, and GPIOs that can be used for LED controls or other general purpose interface configurations.

The Ethernet Switch controller performs the majority of the switch functions of the AR9331. The controller contains five 10/100 Mbps Fast Ethernet ports, each containing four levels of Quality of Service, 802.1Q VLANs, port based VLANs and RMON statistic counters. The AR9331 integrates five 10/100 two speed Ethernet transceivers (PHYs) and one single port 10/100/1000 media access controllers (MAC) as well as a wire-speed, non-blocking shared memory switch fabric.
