ML22Q623
Internal Flash Memory Type

The ML226xx series is speech synthesis LSI with 4Mbit to 32Mbit flash memory.
The large capacity memory is ideal for long audio playback such as voice guidance. Flash memory allows easy rewriting of audio data,  it also has a function to rewrite sound data from the MCU.
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.
