The ML2272X(ML22725/ML22724/ML22723-XXX) are speech synthesis LSIs with built-in P2ROM that stores speech data.
These LSIs include speech speed conversion, pitch conversion, edit ROMs, ADPCM2 decoders, 16-bit DA converters, low pass filters, and monaural speaker amplifiers. The ML2272X supports the synchronous serial interface. By integrating all the functions required for speech output into a single chip, these LSIs can be more easily incorporated in compact portable devices.
