W528X
ADPCM VOICE SYNTHESIZER
(PowerSpeech)
Publication Release Date: May 1997
Revision A6
- 1 -
GENERAL DESCRIPTION
The W528X family are programmable speech synthesis ICs that utilize the ADPCM coding method to
generate all types of voice effects.
The W528X'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 W528X family includes the W5281, W5282, W5283, W5284, W5289, W5285, W5286, W5287,
and W5288. The ROM size of each of these products is shown below:
