w566bxxx 3s/3hq speech+melody processor (banddirector tm series) publication release date: ap ril 2 4 , 2002 - 1 - revision a 1 1. general descripti on the w566bxxx is a powerful embedded microcontroller ( m c) 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 ( m p) 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 (t - melody) pl us 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 c onverted 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 w 566bxxx 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. following table depicts the w 566bxxx series. part# w566b025 W566B030 w566b040 w566b060 w566b080 w566b100 w566b120 rom (byte) 94k 108k 126k 200k 254k 328k 382k ram (byte) 256 256 256 256 256 256 256 operating speed 8/4 mhz 8/4 mhz 8/4 mhz 8/4 mhz 8/4 mhz 4 mhz 4 mhz duration1 (se c) 1 25" 30" 36" 61" 80" 105" 124" duration2 (sec) 2 19? 23? 27? 46? 60? 79? 93? in : bid 3 4 : 16 4 : 16 4 : 16 4 : 16 4 : 16 0 : 16 0 : 16 speaker dac dac dac dac dac dac dac mixer inputs 4 4 4 4 4 4 4 speech tracks 4 3 3 3 3 3 3 3 speech algorithms adpcm mdpcm pcm adpcm mdpcm pcm adpcm mdpcm pcm adpcm mdpcm pcm adpcm mdpcm pcm adpcm mdpcm pcm adpcm mdpcm pcm melody tracks 3 3 3 3 3 3 3 instrument types hq tone voice hq tone voice hq tone voice hq tone voice hq tone voice hq tone voice hq tone voice ir - carrier number of system clocks 2 2 2 2 2 2 2 power management hold stop hold stop hold stop hold stop hold stop hold stop hold stop
