BandDirector™ Family

Part No. W567Bxxx
Datasheet W567Bxxx.pdf
Description The W567Bxxx is a powerful microcontroller (uC) dedicated to speech and melody synthesis applications. With the help of the embedded 8-bit microprocessor & dedicated H/W, the W567Bxxx can synthesize 4-channel speech+melody simultaneously.
The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The W567Bxxx can provide 4-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 W567Sxxx is very suitable for high-quality and sophisticated scenario applications.
The W567Bxxx is also capable of transmitting infrared (IR) signals with on-chip carrier generator. As a result, toys can be designed to interact with each other for more play values. A serial interface can be supported as external memory for memory expansion or content-updateable applications.
