AT73C204
Description
The AT73C204 device provides an integrated power management solution for the add-
on 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 multi-
media 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.
The AT73C204 is suitable for any telecommunications standard: GSM/GPRS, PDS,
CDMA, CDMA2000, WCDMA or UMTS. It is packaged in a small form-factor 49-ball
5 mm x 5 mm BGA package.
