W567Cxxx Voice + Wave table Melody Synthesizer IC

The W567Cxxx provides at most 24 bi-directional I/Os, maximum 512 bytes RAM, IR carrier, Serial Interface Management, and 32KHz-Divider for more and more sophisticated applications, such as interactive toys, cartridge toys and final count down function. 3 LED output pins with 256-level control means that numerous combination of RGB colors may result in a versatility of colorful effects. In addition, W567Cxxx also provides PWM mode output to save power during playback and Watch Dog Timer to prevent latch-up situation occurring.

The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The W567Cxxx can provide 16 -channel high-quality WinMelody? , which can emulate the characteristics of musical instruments, such as piano and violin. The output of speech/melody channels are mixed together through the on-chip digital mixer to produce colorful effects. With these hardware resources, the W567Cxxx is very suitable for high-quality and sophisticated scenario applications.

The W567Cxxx is a powerful microcontroller (?C) dedicated to speech and melody synthesis applications. With the help of the embedded 8-bit microprocessor & dedicated H/W, the W567Cxxx can synthesize 16 -channel speech+melody simultaneously.
