w567bxxx - 2 - 1. general description the w567bxxx 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 w567bxxx can synthesize 4-channel speech+melody simultaneously. the two channels of synthesized speech can be in different kinds of format, for example adpcm and mdpcm. the w567bxxx can provide 4-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 w567sxxx is very suitable for high-quality and sophisticated scenario applications. the w567bxxx is also capable of transmitting infrared (ir) signals with on-chip carrier generator. as a result, toys can be designed to interact with each other for more play values. a serial interface can be supported as external memory for memory expansion or content-updateable applications. the w567bxxx family contains several items with different playback duration as shown below: (@5-bit mdpcm algorithm, 6khz sampling rate) item W567B010 w567b015 w567b020 w567b030 w567b040 *duration 14 sec. 18 sec. 26 sec. 35 sec. 52 sec. item w567b060 w567b080 w567b100 w567b120 w567b150 duration 60 sec. 104 sec. 116 sec. 129 sec. 163 sec. item w567b170 w567b210 w567b260 duration 197 sec. 232 sec. 264 sec. note: *: the duration time is based on 5-bit mdpcm at 6khz sampling rate. the firmware library and timber library have been excluded from user?s rom space for the duration estimation.
