ML22660
External Memory - Internal AB-class/D-class Speaker Amplifier Type

The ML22620 / ML22660 is a speech synthesis LSI that is optimal for long playback because a maximum of 128 Mbit serial memory can be connected externally.
The HQ-ADPCM, 16-bit D / A converter, and low-pass filter that achieve high sound quality are adopted, and a 1.0W monaural speaker amplifier for directly driving speakers is built-in.
Since the functions required for audio output are integrated on a single chip, audio functions can be easily realized simply by adding this LSI.
