The W9986D is a highly integrated USB MPEG audio decoder chip with Digital Voice Recorder (DVR) function built-in. This MPEG Layer III audio decoder is capable of decoding layer III compressed streams, as specified in MPEG 1 and MPEG 2 ISO standards. And W9986D also has integrated many peripheral controllers such that it can directly interface to audio codec, flash memory, USB, etc, to minimize PC board area and system cost.
