The W567CP260 is a powerful microcontroller (μC) dedicated to speech and melody synthesis applications. With 8Mbit embedded OTP, the help of 8-bit microprocessor, it can synthesize 16-channel speech+melody simultaneously.

The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The W567CP260 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 W567CP260 is very suitable for high-quality and sophisticated scenario applications.

The W567CP260 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, W567CP260 also provides PWM mode output to save power during playback and Watch Dog Timer to prevent latch-up situation occurring.

W567CP260 is the OTP chip for the W567C series. It covers the correspondent items in the duration of less than 260 seconds and provide only one DAC/PWM ( doesn’t support W567Cxx6 items)
