BGW200 low-power wlan sip complete, single-package 802.11b solution for mobile handheld devices optimized for low-power mobile applications, this complete, single-package 802.11b solution combines a baseband/mac, rf transceiver, and power ampli?er into an ultra-small (150 mm 2 ) package. it delivers the industrys lowest power consumption in standby mode and supports coexistence with bluetooth ? solutions. s e m i c o n d u c t o r s the BGW200 is a complete, low-power 802.11b wireless lan (wlan) system-in-a-package (sip) solution optimized for battery-powered hand - held devices. it enables consumers to connect to the growing number of wlan networks in of?ces, homes, and public places. it also allows service providers to increase their network reach and customer base, enabling complementary data and voice services across cellular/pcs and wlan networks. coexistence support for bluetooth 1.1 and 1.2 enables seamless integration with philips bluetooth solutions. the sip format, with its complete system functionality, delivers quicker design cycles, lower risk, simpli?ed manufacturing, and a reduced bill of materials. the single-package format also simpli?es assembly and testing, and reduces yield losses. the sip delivers a complete, fully tested imple - mentation of 802.11b functionality, so development teams can focus their energy on innovative product design instead of solving complex issues related to rf layout. ultra-small footprint, ultra-low power consumption the BGW200 uses a single, 68-pin hvqfn-like package that measures only 10 x 15 x 1.3 mm. the entire 802.11b solution requires only three external components and uses less than 180 mm 2 of circuit board area. the BGW200 incorporates several features that decreases power con - sumption. there is an integrated arm7 processor, 1.25 mbytes of sram, 256 kbytes of rom, optimized host interfaces (sdio/spi), and integrated power management hardware/software algorithms. the result is the lowest standby power consumption in the industry (less than 2 mw). superior no host load architecture the BGW200 is designed to place no load on the host processor, so mobile devices can integrate wlan functionality without compromis - ing application performance or battery life. the BGW200 only interfaces key features ? advanced, single-package wlan sip optimized for mobile handheld devices C no rf-critical design required C low total cost of ownership ? lowest power consumption in standby mode: < 2 mw (typ) ? ultra-small form factor C low-pro?le 68-pin hvqfn-like sip package (10 x 15 x 1.3 mm) C only three external components for entire solution ? no host load design delivers easy integration and longer battery life C host processor sleeps while BGW200 processes beacons C BGW200 wakes the host processor only upon data packet arrival ? co-exists with bluetooth 1.1 and 1.2 ? complete software drivers, utility, and diagnostic tools applications ? smartphones, cellular phones, voip wireless phones ? pdas, handheld computing devices, wlan adapter cards (secure digital) ? portable audio/video devices, mp3 players ? other handhelds and electronic devices for wireless digital, audio, multi - media, and telephony
BGW200 low-power 802.11b sip with baseband/mac and rf transceiver for mobile handhelds s e m i c o n d u c t o r s with the host processor when a valid data packet is received. so the host processor is allowed to sleep while the BGW200 independently processes 802.11 beacons. the mac protocol runs on an embedded arm7 processor, for zero overhead on the host processor. an instruction prefetch unit enhances the performance of the arm7. to support new mac protocol features, the BGW200 is also designed to support ?rmware upgrades. bluetooth coexistence the BGW200 is designed to support collaborative coexistence between 802.11 and bluetooth 1.1 and 1.2. a dedicated software and hardware interface implements packet traf?c arbitration (pta) with voice priority between the BGW200 and the bluetooth system. an auto shutdown feature ensures that bluetooth voice takes priority over other signals and there is special support for burst and fragmented frames. bluetooth 1.2 enhances coexistence further, by adding independent adaptive frequency hopping (afh) capability. the philips bgb20x family of bluetooth sips is designed to interface and coexist seamlessly with the BGW200. supports latest qos and security standards advanced hardware and software algorithms, along with wi-fi multi - media extensions (wme), provide advanced quality of service (qos) functions. this lets the BGW200 support real-time applications like voip and non-real-time applications like email and web sur?ng. the BGW200 is also designed to support the upcoming 802.11e standard. the BGW200 has advanced security features, including 40- and 128-bit wep, wpa, ccx (cisco security), tkip, and aes. the sip is also de - signed to support the upcoming 802.11i extension. advanced rf subsystem the integrated rf transceiver supports transmit output power control from +8 to +18 dbm at the antenna port C enabling optimal range, throughput, and power consumption. the integrated rf transceiver uses a direct conversion radio architecture that minimizes external compo - nents and eliminates the if ?lter. for additional component reduction, the integrated pa is internally matched to the zif radio. in addition to the radio transceiver and power ampli?er, the BGW200 also integrates an rx/tx diversity switch, bandpass ?lter, balun, power supply decou - pling, and other passive components. reference designs and eval kits reference design software drivers support pocketpc? and linux? operating systems. drivers for palm? and symbian? are in develop - ment. the BGW200 is backed by a complete set of software utility and diagnostic tools, and is available in evaluation kits. frequency bands 2.4 to 2.5 ghz modulations dbpsk, dqpsk, cck (dsss) data rates 1, 2, 5.5, 11 mbps sip power consumption (typical) tx: 731 mw @ 15 dbm rx: 415 mw standby: < 2 mw sleep mode: 0.2 mw table 1 description size part number low-power 802.11b sip 10 x 15 x 1.3 mm BGW200 table 2
