BandDirector™ Family

The W567 J xxx 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 W567 J xxx can synthesize 6 -channel speech+melody simultaneously.

The two channels of synthesized speech can be in different kinds of format, for example ADPCM and MDPCM. The W567 J xxx can provide 6 -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. With these hardware resources, the W567 J xxx is very suitable for high-quality and sophisticated scenario applications.

The W5 67J xxx provides at most 24 bi-directional I/Os, 256 bytes RAM , IR carrier for more , Serial Interface Management and more sophisticated applications, such as interactive toys, cartridge toys and final count down function. 3 LED output pins with 256-level control means that numerous combination of RGB colors may result in a versatility of colorful effects. In addition, W5 67J xxx also provides PWM mode output to save power during playback and Watch Dog Timer to prevent latch-up situation occurring.
