w567sxxx - 2 - 1. general description the w567sxxx is a powerful microcontroller (uc) dedicated to speech and melody synthesis applications. with the help of the embedded 8-bi t microprocessor & dedicated h/w, the w567sxxx can synthesize 8-channel speec h+melody simultaneously. the two channels of synthesized speech can be in di fferent kinds of format, for example adpcm and mdpcm. the w567sxxx can provide 8-channel high-quality winmelody tm , which can emulate the characteristics of musical inst ruments, such as piano and violin . the output of speech/melody channels are mixed together through the on-chip digital mixer to produce colorful effects. the mixer is further processed to drive dual speakers with ster eo effects. with these hardware resources, the w567sxxx is very suitable for high-qualit y and sophisticated scenario applications. the w567sxxx 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. besides, the w567sxxx is equipped with a 4-channel anal og-to-digital converter (adc). with adc, a toy can respond to environment conditions such as temperature or pressure via sensory devices. therefore, toys with adc can behave vividly than ever before. the w567sxxx family contains several items with di fferent playback duration as shown below: (@5-bit mdpcm algorithm, 6 khz sampling rate) item w567s010 w567s015 w567s020 w567s025 w567s030 W567S040 *duration 14 sec. 18 sec. 27 se c. 31 sec. 35 sec. 52 sec. item w567s060 w567s080 w567s100 w567s120 w567s150 w567s170 duration 60 sec. 104 sec. 116 se c. 129 sec. 163 sec. 197 sec. item w567s210 w567s260 w567s301 w567s341 duration 232 sec. 265 sec. 300 sec. 334 sec. note: *: the duration time is based on 5-bit mdpcm at 6 khz samp ling rate. the firmware library and timber library have been xcluded from user?s rom space for the duration estimation.
