W523AXXX
1. GENERAL DESCRIPTION
The W523Axxx family are programmable speech synthesis ICs that utilize Winbonds new high fidelity
voice synthesis algorithm to generate all types of 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.
The W523Axxx family includes 14 kinds of part numbers with same function except for the voice
duration shown below:
