Datasheet for Qualcomm Atheros AR9002U

2.4/5 GHz 2-stream dual-band 802.11n WLAN solution for USB.

Product Overview
The Qualcomm AR9002U UB95 is based on the AR9287 IEEE 802.11b/g/n MAC/baseband/radio and the AR7010 WLAN accelerator.
The AR9287 is a highly integrated single-chip solution for 2.4 GHz 802.11n wireless local area networks (WLANs) that enables high performance 2x2 MIMO configurations for wireless applications demanding robust link quality, maximum throughput and range. The AR9287 integrates a multi-protocol MAC, baseband processor, analog to digital and digital to analog (ADC/DAC) converters, 2x2 MIMO radio transceiver, and PCI Express interface in an all-CMOS device for low power and small form factor applications.
The AR7010 is a highly flexible and cost effective accelerator that provides an embedded 802.11n WLAN access point and client functionality for broadband and consumer electronic platforms. It integrates an embedded CPU with on-chip memory to offload major computation-intensive 802.11 functions, such as encapsulation/decapsulation, aggregation, rate control and beacon management from the host CPU. It will also allow focus on dedicated tasks, increasing the overall system performance with the lowest RBOM impact. It is an ideal solution for platforms where the host CPU has limited processing bandwidth.
When used in a single design, the AR9002U chip set enables a low-cost, compact solution with USB interface.
