For the Value Added Service (VAS) and feature phone market, this design, an ARM9-based GSM/GPRS/EDGE multimedia platform, provides maximum product flexibility and easy differentiation. It offers guaranteed telecom performance along with integrated messaging, connectivity, and extensive multimedia features.  Key features State-of-the-art GSM/GPRS/EDGE platform Quad-band GPRS/EDGE class 10 Release 99 Modem compliant with latest GCF and PTCRB tests Fully validated Interoperability Testing (IOT) More than 200 million Nexperia cellular system solutions already deployed High-performance multimedia features Video recorder MPEG4/H263, 15 fps QCIF with high quality mode (128 kbps) Media player for video, MP3, AAC, and AAC+ Audio/video streaming and progressive download High-performance JAVA that is fully JTWI compliant Software polyphony DRM 1.0 Advanced integrated connectivity features Bluetooth 1.2 with large set of profiles Low-power WLAN 802.11b Near Field Communication (NFC) USB 2.0, IrDA, MMC/SD/T-Flash card Supported by Nexperia Mobile Developers Kit 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, making these platforms some of the most extensively proven designs available. The NXP core chipset includes a Nexperia multimedia baseband, an RF transceiver, a power management unit, and a battery charger. The protocol stack includes an extendable man-machine interface (MMI) and is fully tested for interoperability with the application hardware. The result is an optimized design that provides outstanding standby and connection time. The Nexperia cellular system solution 6120 includes several ICs that raise the core chipset to a higher level of multimedia performance. There is an image processor, with dedicated power-management circuitry, that previews, captures, stores, and manipulates still images and video clips. This IC, part of a two-chip solution that includes a display driver, supports displays with up to 262k colors and resolution of up to QCIF+ (176 x 220 pixels). There is also a built-in low-power FM radio IC that can be used with US, European, and Japanese bands. For wireless connectivity, the Nexperia cellular system solution 6120 has built-in options for Bluetooth, WLAN, and even Near Field Communication (NFC). Nexperia cellular system solutions combine mature, proven pipe technologies — created using the right process technologies — with the latest value-added features. The result is a portfolio that enables a range of handsets that deliver excellent performance in the field. The Nexperia Mobile Developers 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. To help customers design the right products quickly, we offer an extensive support network of software engineers and cellular experts working in locations throughout the world, with a particularly strong presence in Asia. We combine this field support with regularly held training sessions, for hands-on learning. |
