w561xxx 4-ch melody with voice synthesizer (banddirector tm family) publication release date: february 1999 - 1 - revision a2 general description the w561xxx is one of the derivatives of the banddirector tm familiy. it consists of a 4-bit c, two voice synthesizers, one 4-ch melody generator, and one shared rom. the muti-tasking operation for voice synthesis and 4-ch melody generation is implemented by dedicated h/w that can output the speech voice in parallel with the background music. with the 4 bit kernel, which can execute instructions of up to 12 kips (kilo-instructions per second), and high quality dual speaker output, you will be amazed at the possible applications. w561xxx provides you with a total solution in one chip. in addition, the w561xxx's user-friendly development environment can effectively reduce your design period and help you easily tool your projects by yourself with the ice and emulation kit. there are 10 kinds of w561xxx ic bodies (see table below). part no. w561s15 W561S20 w561s25 w561s30 w561s40 duration 15 sec 20 sec 25 sec 30 sec 40 sec part no. w561s50 w561s60 w561s80 w561s99 w561m02 duration 50 sec 60 sec 80 sec 100 sec 120 sec note: the voice durations are estimated by 8.0 khz sampling rate possible applications are: ? programmed voice synthesis with background music or speech ? i/o interactive voice synthesis to accompany background music or speech ? demo of music songs with possible dynamic timbre/tempo changes during playback ? q&a games ? edutainment toys features ? multi-engine processor parallel management with c, speech and pcm melody ? c // (synthesizer1 or 4-ch melody) // synthesizer2 (//: in parallel) ? c, with basic alu, 64-nibble ram (including 8 working registers) and an 8-bit timer ? synthesizer1 capable of voice syntheses with sample rate @4.8/6/8/12 khz ? synthesizer2, same as synthesizer1 ? 4-ch melody with total 16 kbyte timbre table, which can store up to 16 kinds of timbre samples. ? the on-chip rom is shared among program, voices and melody notes ? wide operating voltage range: 2.4 to 5.5 volts ? low power consumption (v dd = 5 volt) ? standby current < 2 a
