W528S30
Overview
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 userprogrammable functions that make this chip suitable for an extremely wide range of speech IC applications.
