AS3525A

Overview

The AS3525A is an advanced audio processor system-on-chip manufactured by ams-OSRAM USA INC. It integrates a powerful ARM9TDMI core capable of up to 200 MIPS, supporting MP3, AAC, WMA, and OGG decoding. The device utilizes 0.13µm process technology with on-chip RAM for low power consumption, achieving as low as 58mW during MP3 playback. It features dedicated high-speed interfaces including ATA IDE, USB 2.0 HS-OTG, SDRAM, NAND flash, MMC/SD, and Memory Stick. Two independently programmable PLLs manage frequencies for audio, the processor core, and USB simultaneously.
