W523SXX (PRELIMINARY)
HIGH FIDELITY PowerSpeechTM
GENERAL DESCRIPTION
The W523Sxx 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 W523Sxx’ 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 W523Sxx family includes 14 kinds of bodies which are the same except for the voice duration
