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 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. 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.
