GENERAL DESCRIPTION
The W523X is a programmable speech synthesis IC that utilizes the ADPCM coding method to generate all types of voice effects. The W523Xs 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.
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 -
