GENERAL DESCRIPTION
ML2282X(ML22825/ML22824/ML22823-XXX) and ML2286X (ML22865/ML22864/ML22863-XXX) are voice synthesis LSIs with built-in P2ROM that stores speech data. These LSIs include edit ROM, ADPCM2 decoder, 16-bit DA converter, low pass filter and monaural speaker amplifier. Also, ML2282X supports the synchronous serial interface and ML22865/ML22864/ML22863 supports the I2C interface. By integrating all the functions required for voice output into a single chip, these LSIs can be more easily incorporated in compact portable devices.● Built-in memory capacity and maximum vocal reproduction time: (at the case of 4-bit ADPCM2 algorithm) Product name ROM capacity Maximum vocal reproduction time (sec) FS = 4.0 kHz FS = 8.0 kHz FS = 16 kHz ML22825-XXX/ML22865 16 Mbits 1,044 522 261 ML22824-XXX/ML22864 8 Mbits 520 260 130 ML22823-XXX/ML22863 4 Mbits 258 129 64
