This market-proven, ARM7-based design for an ultra-low-cost GSM phone delivers industry-leading standby and talk times. Built-in multimedia features take the phone beyond basic operation, and there are options for easy customization.  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 Sy.Sol systems already deployed Optimized core functionality OM6357 GSM/GPRS baseband with ARM7 core UAA3537 GSM/GPRS RF transceiver BGY502 frontend module PCF50604 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. To increase design flexibility, the handset is available in two formats, as a reference phone or a reference design. The reference phone, designed with a third-party partner, is a production-ready solution that can be brought to market in as little as three to four months from contract signature. It’s the fastest way to get a proven phone to the ULC market, and requires the smallest outlay of design resources. The reference design, which provides a more flexible approach and allows for greater customization, gives design teams a head start and lets them work with partner ODMs and other skilled resources. 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. |
