AS3532 HD Music Player IC is austriamicrosystems’ first member of a new family of media player ICs based on company’s innovative IP aimed at bridging the gap between the audio experience of music phones and Hi-Fi home audio devices. The the core of AS3532 music player IC is based on a newly developed audio engine and audio post-processor which act as co-processors to an ARM CPU. The audio engine supports  popular audio formats such as MP3, AAC and WMA.

The AS3532’s audio post-processor implements an Asynchronous Sample Rate Converter (ASRC) with near transparent quality, a multi-channel mixer with limiting function and a 10 bands graphics equalizer and supports 192 KHz sample rates at 24 bits dynamic range for high definition audio processing. Outputs of three sets of I²S can independently control stereo speakers, headphone subwoofer or line outputs. The AS3532 audio subsystem additionally includes a stereo PDM digital microphone input to accommodate requirements of new generation of mobile phones.

Interfaces included in the AS3532 can support either peer mode to a baseband phone IC or a "Black Box" companion music sub-system. In the latter case, the IC provides direct support for latest generation removable and embedded flash memory types with 4/8/16-bit hardware ECC, for MLC NAND Flash, iNAND, LBA NAND, oneNAND, moviNAND, and removable card formats like SD2.0, MMC+, CE-ATA, CF and MS PRO.

AS3532’s buffer memory (512KByte) allows single chip support of all key audio formats, compressed, lossless and high definition, polyphonic sequenced content, wavetable synthesizer, virtualizer engines, 3D positional sound and other digital audio effects. The AS3532 music player IC is complemented by a comprehensive software suite that has matured over three generations of products delivered in the multimedia player market.
