ML22Q394/ML22Q394P

ADPCM Speech Synthesis LSI

■ GENERAL DESCRIPTION

ML22Q394/ML22Q394P 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,

ML22Q394/ML22Q394P support the I²C 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.
