2 / 17 page W528SXX - 2 - 1. GENERAL DESCRIPTION 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 user- programmable functions that make this chip suitable for an extremely wide range of speech IC applications. The W528Sxx family includes 9 kinds of part numbers with the same function except for the voice duration shown below: ITEM W528S03 W528S05 W528S08A W528S10 W528S12 W528S15 Second 3 Sec 5 Sec 8 Sec 10 Sec 12 Sec 15 Sec ITEM W528S20 W528S25 W528S30 Second 20 Sec 25 Sec 30 Sec Note: The voice durations are estimated by various sampling rate. 2. FEATURES • Programmable speech synthesizer • Wide operating voltage range: 2.4 to 5.5 volts • 4-bit ADPCM synthesis method • Provides 4 direct trigger inputs that can easily be extended to 8 or 12 matrix trigger inputs • Two trigger input debounce times (20 to 40 mS or 160 to 320 µS) can be set • Provides up to 2 LEDs and 3 STOP outputs • Every LED pin can drive 3 LEDs simultaneously • LED flash frequency: 3 Hz • AUD output current: 5 mA • Flexible functions programmable through the following: − LD (load), JP (jump) commands − Four registers: R0, EN, STOP, and MODE − Conditional instructions − Speech equation − END instruction − Global repeat (GR) setting − Output frequency and LED flash type setting • Programmable power-on initialization (POI) (can be interrupted by trigger inputs) • POI delay time of 160 mS ensures stable voltage when chip is powered on • Can be programmed for the following functions: |
