Product Summary
The MSM9810B is an 8-channel mixing voice synthesis LSI, to which up to 128 Mbits of ROM and/or EPROM storing voice data can directly be connected externally. The MSM9810B 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 MSM9810B contains a 14-bit D/A converter and LPF. The device can easily configure a system by connecting voice data storage memory, power amplifier, and CPU externally.
