Preliminary W58100
ADPCM VOICE SYNTHESIZER
ROM-LESS ENHANCED
PowerSpeech
Publication Release Date: December 1996

Revision A1
GENERAL DESCRIPTION
The W58100 is a CMOS IC that is used solely for the purpose of demonstrating the W581xx series
enhanced
PowerSpeech
products.
The W58100 employs the same JUMP-GO architecture as Winbond's other
PowerSpeech
products.
Unlike standard products, however, the W58100 does not include built-in memory, because the chip is
designed to serve only as a demonstration chip for the W581xx series ICs. Hence the W58100 must
be operated with an external memory device (e.g., a flash EPROM memory IC). The W58100's LOAD
and JUMP commands and 8 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: 2.4 to 5.5 volts
Serves as a demo chip for W581xx series products (no built-in ROM)
Programmable speech synthesizer
4-bit ADPCM synthesis method and 8-bit D/A converter
Maximum 4 trigger inputs
Fading effect (patent pending) control for each voice segment
Maximum two LEDs, and five STOP outputs
Flexible functions programmable through the following:
LD (load), JP (jump) commands
8 general registers: R0
R7
Three special registers: EN, STOP, and MODE
Conditional instructions
Speech equation
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 equations
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)
CPU interface
The following mask options are available:
