AS3524

AS3524 C21 / C22 Data Sheet, Confidential austriamicrosystems AS3524 Advanced Audio Processor System å 1 Description The AS3524 implements a highly flexible and fully integrated digital audio processor system combining strong calculating power and high performance interfaces commonly used within audio player systems. Using advanced 0.13µm process technology and large on chip RAM leads to outstanding low power consumption of 0.3 mW/MHz for the ARM922T microcontroller core and 0.6 mW/MHz for the overall system measured with a typical MP3 player SW application. Based on a powerful ARM9TDMI capable of performing up to 200MIPS it is suited to run MP3, AAC, WMA, OGG… decoders and encoders and, in addition, it can perform extensive user interfaces, motion graphics support, video playback and much more. The AS3524 SOC (system-on-a-Chip) features dedicated high speed interfaces for ATA IDE, USB2.0 HS-OTG and SDRAM ensuring maximum performance for download, upload, and playback. Furthermore interfaces for NAND flashes, MMC/SD cards and Memory Stick ensure most flexible system design possibilities. Hardware support for parallel interfaces lower the CPU load serving complex and/or colour user interfaces. Additional serial high-speed data and control interfaces guarantee the connection to other peripherals and or processors in the system. Two independently programmable PLLs generate the required frequencies for audio playback/recording, for the processor core and for the USB interface a...
