W566BXXX
3S/3HQ SPEECH+MELODY PROCESSOR
(BandDirector
TM
Series)
1. GENERAL DESCRIPTION
The W566Bxxx is a powerful embedded microcontroller (碌C) dedicated for speech and melody
synthesis application. This series IC is tailored for plush toy, educational toy or music instrument. With
the help of 16 bits microprocessor (碌P) W566-16, the W566Bxxx 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, W566Bxxx can provide 2-track of Tone melody (T-
melody) plus 2-track percussion sound (2T+2Per), or 3-track of
High-Quality melody (HQ-melody)
that
can emulate the characteristics of musical instruments. These signals can be mixed flexibly through 4-
input Mixer to produce colorful effect. The result of Mixer is converted to analog signal to drive speaker
output.
W566Bxxx 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 W566Bxxx 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, W566Bxxx can
sink 8mA at most for high-current application.
Following table depicts the W566Bxxx series.
