W567SXXX
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 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. 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)

Note: *: The duration time is based on 5-bit MDPCM at 6 KHz sampling rate. The firmware library and timber library have
been xcluded from user’s ROM space for the duration estimation.
