W566BXXX

The W566Bxxx is a powerful embedded microcontroller (mC) 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 (mP) 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 (Tmelody) 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.
