1. GENERAL DESCRIPTION
The W566Bxxx is a powerful embedded microcontroller (
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 (
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.

Notes:
1. The Duration1 is calculated based on 6000Hz*4-bits = 24 Kbps, 24 Kbps on the assumption that all the ROM space is used
to store speech data.
2. The Duration2 is calculated based on 8000Hz*4-bits = 32 Kbps, 32 Kbps on the assumption that all the ROM space is used
to store speech data.
3. "In" is the number of input pins; "Bid" is the number of I/O pins.
4. Synthesized speech in ADPCM/MDPCM format.
