W523X

Power Speech LOW VOLTAGE

ADPCM VOICE SYNTHESIZER

GENERAL DESCRIPTION

The W523X is a programmable speech synthesis IC that utilizes the ADPCM coding method to

generate all types of voice effects. The W523X'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 W523X family includes the W5231, W5232, W5233, and W5234. The ROM size of each of these

products is shown below:

FEATURES

• Wide operating voltage range: 1.2 to 3.6 volts

• Programmable speech synthesizer

• 4-bit ADPCM synthesis method and 8-bit D/A converter

• RC oscillator with built-in capacitor; voice output frequency typically at 6 KHz

• Provides 4 trigger inputs

• Drives 2 flash LEDs for two batteries

• 3 STOP output signals

• Flexible functions programmable through the following:

− LD (load), JP (jump) commands

− Four registers: R0, EN, STOP, and MODE

− Conditional instructions

− Speech equation

− Global repeat (GR) setting

• Programmable power-on initialization (POI), which can be interrupted by trigger inputs

• Interrupt or non-interrupt for rising or falling edge of each trigger pin (this feature determines

retriggerable, non-retriggerable, overwrite, and non-overwrite features of each trigger pin)

• LED On/Off control can be set independently in each GO instruction of speech equation

• Independent control of LED1 and LED2

• Total of 256 voice group entries available for programming

(including eight hardware and 248 software group entry points)

• 20 to 40 mS debounce time

Publication Release Date: March 1996

Notes:

1. In principle, the playing speed determined by ROSC should correspond to the sampling rate during the coding phase.

The playing speed may be adjusted by varying ROSC, however.

2. Rs is an optional current-dividing resistor. If Rs is added, the resistance should be between 470 and 750 Ω.

3. R is used to limit the current on the LED.

4. Cs is optional.

5. The DC current gain β of transistor 8050 ranges from 120 to 200.

6. All unused trigger pins can be left open because of their internal pull-high resistance.

7. No warranty for production!
