1. GENERAL 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^TM, 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.

The W567Bxxx family contains several items with different playback duration as shown below: (@5-bit
