ML22Q284

ADPCM Speech Synthesis LSI for Automotive

■ GENERAL DESCRIPTION

ML22Q284 is a speech synthesis LSI supporting an in-vehicle quality that incorporates Flash for storing voice code data,

and can be controlled with a standalone 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.
