High-compression voice-synthesis IC enables extended playback

ROHM’s BU6930FV is a voice synthesis IC which can play back highly-compressed voice/audio data stored in an external SPI-interface ROM, using commands from a serial interface or from the pins.

A maximum of two channels of voice/audio data can be decoded and played back simultaneously. A one-channel version is also available with part number BU6929FV.

The BU6929FV and BU6930FV feature a 16-bit DAC core for CD-quality sound, whilst the BU6930FV also offers twice the playback time of conventional products due to its compression technology. In addition, the two-channel simultaneous playback capability delivers rich, high-fidelity sound reproduction. Both devices feature auto fade-in/fade-out functionality for smooth voice synthesis.
