GENERAL DESCRIPTION
The W566Cxxx is a powerful embedded microcontroller (uC) dedicated to speech and melody synthesis
applications. This series IC is tailored for plush toys, educational toys, or musical instruments. In multi-tasking
requirements, W566Cxxx series can make toy more funny than before. With the help of 16-bit microprocessor
(uP) W566-16, W566Cxxx can synthesize multi-channel speech and melody. 3-track of synthesized speech
can be in different kinds of format, for example ADPCM and MDPCM. Regarding synthesized melody,
W566Cxxx can provide 4-track of Tone melody (T-melody), or 3-track of
High-Quality melody (HQ-melody)
that
can emulate the characteristics of musical instruments. These signals can be mixed flexibly through 6-input
Mixer to produce colorful effects. The result of Mixer is converted to analog signal to drive speaker output.
W566Cxxx has two kinds of power saving modes: one is HOLD mode and the other is STOP mode. In
HOLD mode, the specific peripherals can be inactivated and IC can operate at the sub-clock. Consequently,
the W566Cxxx can perform some special tasks periodically. In STOP mode, all the IC's peripherals are
disable which is designated specially for try-me application. Besides, W566Cxxx can sink 8mA at most for
high-current application.
The characteristics of W566Cxxx series are depicted in the following table.
