Description

The Atheros AR9344-DC3A is a highly integrated and feature-rich IEEE 802.11n 2×2 2.4/5 GHz Systemon-a-Chip (SoC) for advanced WLAN platforms. It includes a MIPS 74Kc processor, PCI Express 1.1 Root Complex and Endpoint interfaces, five port IEEE 802.3 Fast Ethernet Switch with MAC/ PHY, one MII/RMII/RGMII interface, 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, two UARTs, and GPIOs that can be used for LED controls or other general purpose interface configurations.

The AR9344-DC3A supports 802.11n operations up to 144 Mbps for 20 MHz and 300 Mbps for 40 MHz respectively, and 802.11a/b/g data rates. Additional features include Maximal Likelihood (ML) decoding, Low-Density Parity Check (LDPC), Maximal Ratio Combining (MRC), Tx Beamforming (TxBF), and On-Chip One-Time Programmable (OTP) memory.
