| POWER MANAGEMENT PRODUCTS AT73C212 POWER MANAGEMENT UNIT MID-LEVEL MULTIMEDIA MODULES FOR Integrates in a single IC the power management circuitry for camera and sound sections in feature phones Image: Haz'art Studio l l l 5 independent linear voltage regulators optimized for supplies to memory modules, camera modules and sound generators Step-down DC-DC converter for supplies to co-processor core Over- and under-voltage protection l l l Over-temperature protection All voltage levels customized by mask option Ultra-thin 5mm x 5mm 32-ball FBGA package or 5mm x 5mm 32ball QFN package The AT73C212 illustrates Atmel's product synergy in multimedia phones: Atmel supplies a multimedia coprocessor (AT76C210), CMOS camera module (AT76C45x), and MP3 sound generator (AT8xC51SND1C). The AT73C212 powers all of them. R AT73C212 Corporate Headquarters Atmel Corporation 2325 Orchard Parkway San Jose, CA 95131, USA Tel: (+1) (408) 441-0311 Fax: (+1) (408) 436 4200 POWER MANAGEMENT CONTROLLER The AT73C212 is the second member of Atmel's power management IC family specially designed for the add-on multimedia features in new-generation mobile phones and PDAs. These features include a camera module (CMOS or CCD), sound system for polyphonic ringing tones or MP3 playing, memory module for downloaded MP3 files, external MMC card, etc. AT73C212 Osc DC-DC Converter Co-Processor Power Supply Europe Atmel SarL Route des Arsenaux 41 Casa Postale 80 CH-1705 Fribourg Switzerland Tel: (+41) 26-426-5555 Fax: (+41) 26-426-5500 VREF Voltage Regulator 1 Voltage Regulator 2 Voltage Regulator 3 VOUT1 VOUT2 Asia Atmel Asia Ltd Room 1219 Chinachem Golden Plaza 77 Mody Road,Tsimshatsui East Kowloon Hong Kong Tel: (+852) 272 19 778 Fax: (+852) 272 21 369 VOUT3 Voltage Regulator 4 Main Battery VOUT4 Voltage Regulator 5 VOUT5 Japan Atmel Japan KK Tonetsu Shinkawa Bldg, 9F 1-24-8 Shinkawa Chuo-Ku, Tokyo 104-0033 Japan Tel: (+81) 3 3523 3551 Fax: (+81) 3 3523 7581 AT73C212 Block Diagram The AT73C212 helps mobile phone manufacturers save space on their PCBs. The integration of multimedia features such as camera and sound requires an additional set of power supplies besides the traditional main power management unit. The AT73C212 is able to supply a camera with 2.8V (LDO1) and sound decoder with 1.8V (DC/ DC) for core and 2.8V (LDO2) for I/O. USB is supplied with 3.0V (LDO3) and external memory module can be connected to 2.8V (LDO4). Audio analog interface like stereo DAC can be directly supplied by separate 2.8V (LDO5) increasing analog performances. Finally a highefficiency 300mA step down DC/DC converter completes the system by supplying the imaging co-processor. All voltages are metal programmable and allow a customer to find in the Atmel standard product portfolio their specific requirement to supply the multimedia section of their feature phone in the most cost effective, space saving manner. The AT73C212 is now available in a 5 x 5 mm, 32ball ultra-thin BGA package in order to satisfy portable device manufacturers' minimum space requirements. It is also available in a 5 x 5 mm, 32-pin QFN package for a reduced number of PCB layers.
