Overview

FEDL22420FULL-05 Issue Date: August.
25, 2011 ML22420MB/ML22460MB Speech Synthesis LSI with Serial ROM Interface Including 4-Channel Mixing Function GENERAL DESCRIPTION ML22420 and ML22460 are voice synthesis LSIs with serial interface to the external ROM that stores voice data.
These LSIs include edit ROM, ADPCM2 decoder, 16-bit DA converter, low pass filter and monaural speaker amplifier.
Also, ML22420 supports the synchronous serial interface and ML22460 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.
• Maximum External ROM capacity: 128Mbits • External ROM capacity and maximum vocal reproduction time: (at the case of 4-bit ADPCM2 algorithm) External Maximum vocal reproduction time (sec) ROM capacity FS = 4.
0 kHz FS = 8.
