8-channel Mixing OKI ADPCM Type Voice Synthesis LSI

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.
