ML2011 integrates an MP3 decoder and speaker amplifier in a single chip with wafer level chip size packaging (W-CSP), achieving the world's smallest package of 3.6 x 4.2mm. In addition to the LSIs, Oki provides a reference board and a sample of its embedding software enabling users to achieve MP3 systems easily.
As the use of digital audio players and mobile phones equipped with music playback functions grows, demands for systems equipped with digital audio functions, such as MP3, has also been increasing. Oki successfully integrates the speaker amplifier, achieving a highly functional, low cost chip with the smallest size packaging in the world.
Oki's ML2011 is compliant with all MP3 formats including MPEG 1 Audio Layer III, MPEG 2 Audio Layer III and MPEG2.5, enabling users to replay a wide range of sounds from fully compressed voice to high-quality music. The 8ohm speaker amplifier has an output of 650mW and is designed to operate on 5V. Naturally, the chip is compliant with the MP3 decoder. It comes in two sizes: the world's smallest packaging of 3.6mm x 4.2mm W-CSP, or a 5mm x 6mm QFN package for easy mounting.
Oki also offers the ML2011 reference board , and SoundLib , the sample software for use in embedding. Users can easily connect the ML2011 reference board to their existing system, offering an environment for easy development and evaluation of the software. The use of SoundLib enables users to reduce the time needed for developing embedded software.
While a sound generator replays musical note files by combining pre-installed instrument sounds, the ML2011 , because it is compliant with MP3, can replay both voice and vocals with music accompaniment. In addition, compared to speech LSIs, ML2011 provides better sound quality sound effects and can compress the data by 50%.
