General Description
The Atheros AR9271 is a highly integrated singlechip solution for 2.4 GHz 802.11n-ready wireless local area networks (WLANs) that enables a highperformance 1x1 configuration for wireless station applications demanding robust link quality and maximum throughput and range. The AR9271 integrates a multi-protocol MAC, baseband processor, analog-to-digital and digital-to-analog (ADC/DAC) converters, 1x1 radio transceiver, RF switch, and USB interface in an all-CMOS device for low power and small form factor applications.

Features
■ All-CMOS solution interoperable with IEEE
   802.11b/g/n WLANs
■ Intergrated RF front end with high-output PA,
   LNA, Rx/Tx switch
■ Internal diversity switch which selects antenna
   1 or 2 for baseband signal processing
■ Supports optional external LNA, PA
■ 2.4 GHz WLAN MAC/BB processing
■ BPSK, QPSK, 16 QAM, 64 QAM, DBPSK,
   DQPSK, and CCK modulation schemes
■ Supports 72.2 Mbps for 20 MHz and 150 Mbps
   for 40 MHz channel operations
■ Wireless multimedia enhancements quality of
   service support (QoS)
■ 802.11e-compatible bursting
■ Support for IEEE 802.11e and IEEE 802.11i
   standards
■ WEP, TKIP, and AES hardware encryption
■ Reduced (short) guard interval
■ Frame aggregation
■ Block ACK
■ USB 2.0 interface
■ Supports the access of a serial peripheral (SPI)
   compatible Flash memory, which includes
   booting from an SPI Flash and auto
   installation
■ IEEE 1149.1 standard test access port and
   boundary scan architecture supported
■ 68-pin, 8 mm x 8 mm LPCC package
