1. GENERAL 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.

The W567Sxxx family contains several items with different playback duration as shown below: (@5-bit
MDPCM algorithm, 6 KHz sampling rate)

Notes:

1. The typical value of Rosc is 160 K

for 8 MHz and 320 K for 4 MHz and should be connected to GND (V

2. Please refer to design guide to get typical Rosc value for each part number.
3. For W567S080~S341, V

1 should be connected to V

; and V

1 should be connected to V

in PCB layout.

4. The Rs value is suggested in 270

~ 1K to limit too large DAC output current flowing into transistor.

5. The

and 0.1�F between V

, V

1 and GND are optional to filter power noise.

6. The capacitor, 4.7

�F, shunts between V

and GND is necessary as power stability. But the value of capacitor is

depend on the application.

7. The above application circuits are for reference only. No warranty for mass production.
