AS3524 Advanced Audio Processor System

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 a.

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, fo.
