MC93CV402 [Voice MCU]

MC93CV402 [Voice MCU]

⯀ Description

MC93CV402 is a voice-synthesize IC which has 14-bit digital amplifier inside. MC93CV402 provides narrow band SPEEX and 4-bit ADPCM decoders. SPEEX is a CELP (Code Excited Linear Prediction) based voice en/decoder which is specialized for voice compression, and provides variety of bit rates. MC93CV402 can provide 'Narrow Band' (8 kHz and 12 kHz) sampling frequencies. MC93CV402 also provides 4-bit ADPCM. It is useful to play music or effect sounds. Especially, MC93CV402 is possible to play both SPEEX and ADPCM sound at the same time. It is useful when playing voice with background music. SPEEX and ADPCM sounds can be synthesized with different bit rates and it is possible to control the playing speed and each volume separately. VM (Voice Message) feature is provided, which means it is possible to make a message by synthesizing voices. This is useful to reduce the duplicated voice data. MC93CV402 uses an external SPI Flash for sound data, so the ROM size is selectable.
