GENERAL DESCRIPTION
The W523Sxx family are programmable speech synthesis ICs that utilize Winbond
′
s 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

FEATURES
Operating voltage range: 2.4 – 5.5 volts for both DAC and PWM output
New high fidelity synthesis algorithm
Either PWM mode or D/A converter mode can be selected for AUD output
Provides 4 direct trigger inputs that can easily be extended to 24 matrix trigger inputs
Two trigger input debounce times (50 mS or 400 uS) can be set
Provides up to 2 LEDs and 5 STOP outputs
Flexible functions programmable through the following:
LD (Load), JP (Jump), MV (Move) and INC (Increase) commands
Four general purpose registers: R0, R1, R2 and R3
Six special purpose registers: EN0, EN1, MODE0, MODE1, STOP and PAGE
Conditional instructions: @LAST, @TGn_HIGH or LOW, where, n = 1,2,5 or 6
