W528X Application Note

ADPCM VOICE SYNTHESIZER

(PowerSpeech)

INTRODUCTION

The W528x family are programmable speech synthesis ICs that utilize the ADPCM coding method to

generate all types of voice effects.

The W528x'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. Before developing their own PowerSpeech programs and codes, customers should

review the application notes presented below.

The W528x family includes the W5281, W5282, W5283, W5284, W5289, W5285, W5286, W5287,

and W5288. The ROM size of each of these products is shown below:

FEATURES

· Programmable speech synthesizer

· Wide operating voltage range: 2.4 to 5.0 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 ( Long/ Short ) 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
