W561XXX
4-CH MELODY WITH VOICE SYNTHESIZER
(BandDirectorTM Family)
GENERAL DESCRIPTION
The W561xxx is one of the derivatives of the BandDirectorTM familiy. It consists of a 4-bit µC, 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).

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 µC, speech and PCM Melody
− µC // (Synthesizer1 or 4-CH Melody) // Synthesizer2 (//: in parallel)
− µC, 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 (VDD = 5 Volt)
− Standby current < 2 µA
