TT6297/TT6298

4-CHANNEL ADPCM VOICE SYNTEHSIS LSI

GENERAL DESCRIPTION

The TT6297/TT6298 is a 4-channel mixing ADPCM voice synthesis LSI which offers one

sound outputs with 4 channels . The TT6297/TT6298 can access an external voice data ROM for

sound effects or speech voice. The maximum external ROM size is 16M/8M *8 bit and can

direct access. The TT6297/TT6298 has an 4-channel synthesis stage which allows the

simultaneous playback of four different channels. It is used to have a voice with BGM (Back

Ground Music) effect, instrumental sound, echo effect etc.
