CSR’s UniFi UF6000 is one of the smallest and cheapest Wi-Fi chips you can buy. Occupying only 16 square mm, the chip can be embedded into handsets and other devices where wireless connectivity is needed. 3G wireless broadband technologies give handsets a link to the Internet. But because of its high speed and extensive worldwide net of hotspots, Wi-Fi is the fastest and cheapest way to access the Internet and all its features.
The UF6000 is compatible with the IEEE 802.11n wireless standard and is available in versions for 2.4 GHz only or both 2.4- and 5-GHz Wi-Fi bands. The device supports the 11n standard with Single Spatial Stream, which can deliver data rates to 72 Mbits/s without resorting to the more complex and powerhungry multiple-input multiple-output (MIMO) solutions available.
Also, the UF6000 supports Space Time Block Coding, which provides increased throughput and range in tough RF environments. It complies with 802.11e Quality of Service (QoS), Wi-Fi Alliance WMM (Wi-Fi Multimedia) Power Save, and the 11n power save standards.
The chip comes in a 0.5-mm pitch wafer-level chip-scale package (WLCSP) for chip-on-board designs. When combined with CSR’s BC7830, you can get GPS, Bluetooth, and FM radio along with your 11n Wi-Fi all in an area of less than 27 square mm. The UniFi UF6000 is sampling now.
