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 WinMelodyTM , 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

MDPCM algorithm, 6KHz sampling rate)

Item W567B010 W567B015 W567B020 W567B030 W567B040

*Duration 14 sec. 18 sec. 26 sec. 35 sec. 52 sec.

Item W567B060 W567B080 W567B100 W567B120 W567B150

Duration 60 sec. 104 sec. 116 sec. 129 sec. 163 sec.

Item W567B170 W567B210 W567B260

Duration 197 sec. 232 sec. 264 sec.

Note:

*: The duration time is based on 5-bit MDPCM at 6KHz sampling rate. The firmware library and timber library have

been excluded from user’s ROM space for the duration estimation.
