Британская компания CSR предлагает семейство небольших (16 мм2) и недорогих Wi-Fi кристаллов UniFi UF6000 для встраиваемых приборов. Они позволяют встраивать, при минимальных затратах, 802.11n Wi-Fi в мобильные устройства. При совместном использовании UF6000 с BC7830 GPS и Bluetooth чипом, возможно реализовать Wi-Fi, Bluetooth, GPS и FM трансмиттер на площади в 27 мм2.
CSR UniFi UF6000 Wi-Fi Chips
The CSR UniFi UF6000 Wi-Fi chips are a family of small, low-cost, 802.11n compatible, embedded devices. The UF6000 measures less than 16mm2 in silicon size. According to CSR, the UniFi UF6000 is the lowest cost way of adding an 802.11n enabled Wi-Fi to mobile devices. By combining the UF6000 with their BC7830 GPS and Bluetooth chip, CSR is able to offer customers Wi-Fi, Bluetooth, GPS and FM transmit and receive at a combined silicon area of 27mm2. The UniFi UF6000 range of devices is already being sampled to key tier one customers.
CSR’s UniFi UF6000 Wi-Fi chips offer the lowest cost route to integrate Wi-Fi into handsets without compromising on performance or PCB space. CSR’s UF6000 range supports IEEE 802.11a/b/g and n. By achieving lower cost points for Wi-Fi integration, Wi-Fi can be integrated into mainstream handsets and portable devices where previously the cost was prohibitive.
With a silicon size of less than 16mm-sq, the UniFi UF6000 range is the industry’s smallest 802.11n compatible device. All of the series are available in 0.5mm pitch Wafer Level Chip Scale Packaging (WLCSP), the smallest and lowest cost packaging option. This means that the UniFi UF6000 range can easily be adopted for chip-on-board designs, a key step in lowering the cost for manufacturers to embed Wi-Fi. For module solutions, ultra-thin WLCSP packages can be supplied with an impressive low profile of just 0.35mm. The UniFi UF6000 range is available in either 2.4GHz only or 2.4/5GHz giving complete flexibility to manufacturers in their choice of Wi-Fi.
The UniFi UF6000 range supports IEEE 802.11n Single Spatial Stream, providing high data speeds of up to 72Mbps, enabling mobile devices to benefit from the higher speeds of 802.11n without requiring the multiple power hungry radios of the current 802.11n MIMO solutions. The UniFi UF6000 range also supports technology known as Space Time Block Coding (STBC), which provides state-of-the-art throughput and range in challenging RF environments. The UniFi UF6000 range is fully compliant with IEEE802.11e QoS, Wi-Fi Alliance WMM Power Save and 802.11n power saving, ensuring the lowest possible power consumption.
