GENERAL DESCRIPTION
The ML22808/ML22804/ML22802-xxx are speech synthesis LSI devices that have P2ROM for storing voice data.
The voice output component has an ADPCM2 decoder to enable high speech quality, a D/A converter, and a low-pass filter.
It is easy to configure a speech synthesizer by connecting a power amplifier and a CPU externally.
The ML22808/ML22804/ML22802-xxx allow selection of a playback method from among the 8-bit PCM, non-linear 8-bit PCM, 16-bit PCM, and 4-bit ADPCM2 algorithms and enable volume control.
