ML22Q374

ML22Q374 ADPCM Speech Synthesis LSI FEDL22Q374-02 Issue Date: Jun. 06, 2014 GENERAL DESCRIPTION ML22Q374 is voice synthesis LSI with built-in Flash memory that stores speech data. This LSI includes edit ROM, ADPCM2 decoder, low pass filter and D-class speaker amplifier. Also, ML22Q374 support the synchronous serial interface. By integrating all the functions required for voice output into a single chip, this LSI can be more easily incorporated in compact portable devices.
