This market-proven, ARM7-based design for an entry-level GSM/GPRS phone supports three out of four bands on the transceiver side (GSM850, 900, 1800, 1900). A GSM-only variant is also available. The design delivers increased component integration, adding an antenna switch to the power amplifier to create a complete radio front-end. The result is simplified RF tuning and a significantly reduced part count (25 to 30 pieces).  Key features Complete, market-proven design for entry-level GSM/GPRS multimedia handsets Reliable hardware/software solution Fully validated Interoperability Testing (IOT) and GCF/PTCRB tested More than 200 million Nexperia cellular system solutions already deployed Optimized core functionality OM6357 GSM/GPRS baseband with ARM7 core UAA3537 GSM/GPRS RF transceiver BGY502 front-end module PCF50603 PMU and UBA2008 charge switch Core software: drivers/handlers, protocol stack with MMI GSM-only version also available Easy customization with multimedia options MMS 2.0,WAP 2.0, polyphonic tone generation, file system, email, FM radio, Java, SyncML, MPEG4, instant messaging, speech recognition, Bluetooth Dedicated local support and customer training are available Background information This design supports a wide range of multimedia applications and connectivity while minimizing power consumption to deliver industry-leading standby and talk times. Manufactured in very high volume, this cost-effective solution comes fully GCF/PTCRB tested, so OEMs and ODMs can save time while delivering mature, reliable technology. Each Nexperia cellular system solution is a carefully designed combination of powerful core hardware and proven, mature software. More than 200 million Nexperia-based systems have been brought to market and more than one in every ten GSM/GPRS handsets uses a Nexperia solution, which makes these platforms some of the most extensively proven designs available. The core chipset includes a Nexperia multimedia baseband, an RF transceiver, a power amplifier, a power management unit, and a battery charger. The protocol stack includes an extendable man-machine interface (MMI) and is fully integrated with the application hardware. With extensive IOTs, the result is an optimized design that provides outstanding standby and connection times. Built around a highly flexible, platform-based architecture, this design can quickly be extended with multimedia features for completely tailored performance. Design teams can also add their own software, or software supplied by a third party, to the basic system. The Nexperia Mobile Developer’s Kit has all the elements needed to start working with a Nexperia cellular system solution. This simple-to-run yet powerful kit, developed in collaboration with ARM, includes industry-leading ARM tools and uses the popular Metrowerks Codewarrior for its development environment. The Kit is shipped ready to run on a standard Windows PC and includes a self-guided training pack plus a complete set of documentation (with HTML index) that provides extensive reference material. |
