LOW VOLTAGE
ADPCM VOICE SYNTHESIZER
Publication Release Date: March 1996

Revision A2
GENERAL DESCRIPTION
The W5230 is a CMOS IC that is used solely for the purpose of demonstrating W523X series Low
Voltage
PowerSpeech
products.
The W5230 employs the same JUMP-GO architecture as Winbond's other
PowerSpeech
products.
Unlike standard products, however, the W5230 does not include built-in memory, because the chip is
designed to serve only as a demonstration chip for the W523X series ICs. Hence the W5230 must be
operated with an external memory device (e.g., an OTP memory). The W5230's LOAD and JUMP
commands and four programmable registers provide powerful user-programmable functions that make
this chip suitable for a wide range of speech IC applications.
FEATURES
Wide operating voltage range: 1.2 to 3.6 volts
Serves as demo chip for W523X series products (no built-in ROM)
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 LED 1 and LED 2
Total of 256 voice group entries available for programming
(Including eight hardware and 248 software group entry points)
20 to 40 mS debounce time
Provides the following mask options:
