BandDirector™ Family

Part No.	W567Sxxx
Datasheet	N/A
Description	The W567Sxxx 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 W567Sxxx can synthesize 8-channel speech+melody simultaneously. The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The W567Sxxx can provide 8-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. The mixer is further processed to drive dual speakers with stereo effects. With these hardware resources, the W567Sxxx is very suitable for high-quality and sophisticated scenario applications. The W567Sxxx 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. Besides, the W567Sxxx is equipped with a 4-channel Analog-to-Digital Converter (ADC). With ADC, a toy can respond to environment conditions such as temperature or pressure via sensory devices. Therefore, toys with ADC can behave vividly than ever before.
