GENERAL DESCRIPTION

The W523Axxx family are programmable speech synthesis ICs that utilize Winbond′s new high fidelity voice synthesis algorithm to generate all typesof voice effects with high sound quality. The W523Axxx’s LOAD, JUMP, MOVE and INC commands and ten programmable registers provide powerful user-programmable functions that make this chip suitable for an extremely wide range of

speech IC applications.
