The AT73C204 device provides an integrated power management solution for the addon multimedia features in new-generation mobile phones. These features include a camera module, sound system for polyphonic ringing tones, memory module for downloaded MP3 files, Bluetooth module for cordless headset, etc. The most common approach to the IC architecture of these new-generation mobile phones is a baseband processor for the basic telephony functions and a separate co-processor for the multimedia features. Atmel proposes the AT73C202 for power management of the baseband processor and RF elements, and the AT73C204 for power management of the multimedia features.
