W567CXXX Datasheet, PDF (2/13 Pages) List of Unclassifed Manufacturers – 16-CHANNEL SPEECH+MELODY PROCESSOR

W567CXXX
1. GENERAL DESCRIPTION
The W567Cxxx 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 W567Cxxx
can synthesize 16-channel speech+melody simultaneously.
The two channels of synthesized speech can be in different kinds of format, for example ADPCM
and MDPCM. The W567Cxxx can provide 16-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 W567Cxxx is very suitable for high-quality and sophisticated scenario
applications.
The W567Cxxx provides at most 24 bi-directional I/Os, maximum 512 bytes RAM, IR carrier,
Serial Interface Management, and 32KHz-Divider for more 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, W567Cxxx also provides PWM mode output to save power during playback and Watch
Dog Timer to prevent latch-up situation occurring.
