NXP Semiconductors is expanding its range of fully-integrated GSM/GPRS single-chip solutions for the ultralow-cost (ULC) handset market with the Nexperia single-chip solution PNX4902. Representing the ULC+ concept, the solution enables a generation of high-quality, feature-packed cellphones at an ultralow cost point. PNX4902 builds on the commercial success of PNX4901 by adding tri-band capability (850/900, 1800, 1900) for global coverage, Bluetooth support, 8 driver for speakerphone functionality, without the need for an external IC or components, further lowering BOMs cost and extensive support for peripherals, including touchscreen interface and camera (using external co-processor).

Triband, which is largely taken for granted in the feature-phone segment, is a first in the ultralow-cost market and will enable millions of consumers to enjoy the benefits of worldwide mobile access. Bluetooth support, on the other hand, ushers in a new era of connectivity for the ULC+ market, allowing the device to communicate with PCs, hands-free headsets and other phones. The integrated 8 driver provides 500mW of output power, enabling speakerphone functionality without any external components.

According to NXp, the PNX4902 offers best-in-class RF performance and the industry's lowest power consumption. PNX4902 is based on NXP's Aero transceiver technology which has shipped into over 500 million handsets worldwide, and delivers robust RF performance across commonly encountered stress conditions in the field such as extreme temperature changes and declining battery voltage. Excellent call quality is maintained in both congested, urban environments and in remote areas with sparse network coverage. Features such as SAIC further boost an operator's network capacity. NXP touts PNX4902 offers world-class power consumption: a talk time of 5hrs and standby time of 420hrs achievable with a small 600mAh battery. This makes possible handset designs that are slim and yet offer excellent autonomy.

Key features of the Nexperia single chip solution PNX4902 include digital and analog basebands, RF transceiver, power management and audio codec (including high-performance 8 driver) integrated on a single, monolithic CMOS IC. It also has ARM926EJ-STM with Java-Jazelle hardware acceleration. Other features include GPRS data capability (Classes 1-10), WAP browsing, MMS; 40 voice polyphonic MIDI and MP3 ringtones; SD/MMC card support for mass storage and speaker phone noise suppression and echo cancellation. NXO adds the device also offers a mature R99 telecom stack, field-tested in 36 networks, on 4 continents.

The Nexperia PNX4902 ULC solution for GSM/GPRS solution, with enhanced multimedia and connectivity, will be sampling in Q1 and will enter mass production in Q4.
