feature-rich IEEE 802.11n 2x2 2.4 GHz Systemon-
a-Chip (SoC) for advanced WLAN platforms.
It includes a MIPS 74Kc 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, two UARTs, and GPIOs
that can be used for LED controls or other
general purpose interface configurations.
The AR9341 supports 802.11n operations up to
144 Mbps for 20 MHz and 300 Mbps for 40 MHz
respectively, and 802.11b/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.
The AR9341 supports booting from NOR flash.
When connecting the AR9341 to an external host
through the USB Device interface, the AR9341
can offload the host CPU from computationintensive
functions, allowing it to focus on its
dedicated tasks.
