AR9341 - Highly-Integrated and Feature-Rich IEEE 802.11n 2x2 2.4 GHz Premium SoC

General Description

The Atheros AR9341 is a highly integrated and feature-rich IEEE 802.11n 2x2 2.4 GHz Systemon-a-Chip (SoC) for advanced WLAN platforms.

Key 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. Features.
  • 74Kc MIPS processor with 64 KB I-Cache and 32 KB D-Cache, operat.
