Single-chip GSM/GPRS for ULC+

PNX4902 - ultra-low-cost solution with value-added multimedia and connectivity features

This second-generation solution builds on the groundbreaking PNX4901. It delivers enhanced audio integration, value-added multimedia features such as stereo MP3 playback and FM recording, Bluetooth® connectivity and extensive peripheral support. As part of the PNX49xx family, the PNX4902 offers lowest cost of ownership, best-in-class RF performance, longest battery life and robust security. It enables a new class of ULC+ handsets that offer highly desirable features at a greatly reduced price, thus expanding the reach of these technologies to millions more consumers in emerging and developed markets.
