ML22Q294

ADPCM Speech Synthesis LSI for Automotive

■ GENERAL DESCRIPTION

ML22Q294 is a speech synthesis LSI supporting an in-vehicle quality that incorporates Flash for storing voice code data,

and can be controlled with a I²C interface.

By integrating D-class speaker amplifier, solution required for voice output is made possible with single chip.
