ML2282X-XXX/ML2286X-XXX

Speech Synthesis LSI with Built-in P2ROM Including 2-Channel Mixing Function

1/63

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:
