w561xxx - 2 - 1. 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-track pcm- melody generator, and one shared rom. the muti-tasking operation for voice synthesis and 4-track pcm-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 main rom size 640 kbit 768 kbit 896 kbit 1024 kbit 1472 kbit part no. w561s50 w561s60 w561s80 w561s99 W561M02 duration 50 sec 60 sec 80 sec 100 sec 120 sec main rom size 1760 kbit 1920 kbit 3072 kbit 3520 kbit 3968 kbit 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 2. features ? multi-engine processor parallel management with c, speech and pcm melody ? c // (synthesizer1 or 4-track pcm-mel ody) // synthesizer2 (//: in parallel) ? c, with basic alu, 64-nibble ram (includi ng 8 working registers) and an 8-bit timer the w561&w562 user ram initialization value is not constant. it is random. so, user must initial constant value. ? synthesizer1 capable of voice syntheses with sample rate @4.8/6/8/12 khz ? synthesizer2, same as synthesizer1 ? 4-track pcm-melody with total 16 kbyte timb re table, which can store up to 16 kinds of timbre samples.
