RT2571W

RT2571W Data sheet Revision June 22, 2007 Applications IEEE802.11a/b/g Wireless Local Area Networks Wireless Portable Device/Notebook Computer The RT2571W is a highly integrated MAC/baseband processor to support IEEE 802.11a/b/g USB wireless LAN Standards. The processor is part of Ralink chip set RT2501USB for the baseband part, it supports the Direct Sequence Spread Spectrum (DSSS) for 2.4GHz band and Orthogonal Frequency Division Multiplexing (OFDM) for 2.4GHz and 5GHz bands. Using advanced digital signal processing technologies, the optimal reception performance under severe multi-path environments is achieved. For the MAC part, it provides all the required functions and many optional features in the IEEE standards, such as 802.11e (QOS), 802.11h (TPC/DFS), 802.11i (Security). It has many on-chip acceleration engines to ensure that the highest MAC performance is achieved without overloading host processing power. Using advanced algorithms and design methodologies, the chip is best-in-class in terms of throughput, power consumption, range and multipath tolerance. The RT2571W housed in a 180-pin 12*12mm2 TFBGA package is well suited for embedded applications. External Interfaces include USB 1.1/ USB 2.0. Features Host interface: USB1.1 / USB 2.0 Full Implementation of the MAC Protocol specified in IEEE Standards 802.11-1999 and 802.11g and 802.11g-2003 Supported Operating System: Windows XP, Windows2000, Windows ME, 98SE, Linux Security: 64/128 WEP, WPA, AES ...
