GENERAL DESCRIPTION

ML2282X(ML22825/ML22824/ML22823-XXX) and ML2286X (ML22865/ML22864/ML22783-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.

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.
