W528S03 Datasheet, PDF (2/17 Pages) Winbond – ADPCM VOICE SYNTHESIZER

W528SXX
1. GENERAL DESCRIPTION
The W528Sxx family is programmable speech synthesis ICs that utilize the ADPCM coding method to
generate all types of voice effects.
The W528Sxx'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 W528Sxx family includes 9 kinds of part numbers with the same function except for the voice
