AS3525-A/-B C22O22

Data Sheet, Confidential

5 Typical Applications

AS3525 is an advanced audio system-on-a-chip for flash-players, hard-disk players, mobile phones and PDAs powered by single Li+, AA or AAA

batteries.

AS3525-A is the package variant with 224 balls intended for full-featured harddisk players, AS3524-B is the package variant with 144 balls for flash

players with reduced feature set and no need for an external SDRAM.

Two versions are available for the chips: C22O22 which is the newest version with additional boot loader features, and C21O20 which is outdated

and must not be used for new design starts.

5.1 Flash-Player

The following schematic shows a typical flash-player application of the AS3525-B in the CTBGA144 package. A single AAA or AA battery powers

the complete system. The on-chip DC/DC converter generates a supply voltage of 3.25V (BVDD) with a maximum output load current of 150mA.

Linear regulators, which are connected to this BVDD, provide the supply voltages for the analog functions, the USB-2.0-Phy, the digital periphery

and external components. A highly efficient Charge-Pump Step-Down-Converter supplies the digital core. All analog features are available in this

package variant. Also, the digital interfaces to NAND-flash, MMC/SD card, Memory-Stick-Pro, USB-2.0 HS&OTG, Synchronous Serial Interface,

General Purpose IOs and different displays are provided.
