W528SXX
ADPCM VOICE SYNTHESIZER
GENERAL DESCRIPTION
(PowerSpeech)
The W528xxx family are programmable speech synthesis ICs that utilize the ADPCM coding method to
generate all types of voice effects.
The W528xxx's LOAD and JUMP commands and four programmable registers provide powerful user-
programmable functions that make this chip suitable for an extremely wide range of speech IC
applications.
The W528xxx family includes 12 kinds of bodies which are the same except for the voice duration
shown below:
