Speech Synthesis LSI with Built-in P2ROM Including 2-Channel Mixing Function
FEDL228XX-05
Issue Date: Oct. 10, 2013
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.
