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).

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
