GENERAL DESCRIPTION
The MSM9810 is an 8-channel mixing voice synthesis IC, to which up to 128 Mbits of ROM and/
or EPROM storing voice data can directly be connected externally.
The device is straight 8-bit PCM playback, non-linear 8-bit PCM playback, 4-bit ADPCM
playback, and 4-bit ADPCM2 playback selectable and provides 2-channel stereo output and
volume control. The MSM9810 contains a 14-bit D/A converter and LPF.
The MSM9810 can easily configure a system by connecting voice data storage memory, power
amplifier, and CPU externally.
