W5280
ADPCM VOICE SYNTHESIZER
(ROM-less
PowerSpeech
)
Publication Release Date: March 1996
- 1 -
Revision A2
GENERAL DESCRIPTION
The W5280 is a CMOS IC that is used solely for the purpose of demonstrating W528X series
PowerSpeech
products.
The W5280 employs the same JUMP-GO architecture as most of Winbond's other speech
synthesizers. Unlike standard products, however, the W5280 does not include a built-in memory,
because the chip is designed to serve only as a demonstration chip for the W528X series
PowerSpeech
ICs. The W5280 has an ADPCM synthesizer, an 8-bit D/A converter, and all other
necessary control and timing logic, but it must be operated with an external memory device (OTP). The
W5280'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.
FEATURES
Serves as demo chip for W528X series products (no built-in ROM)
Oscillator frequency adjustable by external resistor
Wide operating voltage range: 2.4 to 5.0 volts
4-bit ADPCM synthesizer method and built-in 8-bit D/A converter
Provides 4 direct trigger inputs that can easily be extended to 8 or 12 matrix trigger inputs
Two trigger input debounce time settings (20 to 40 mS or 160 to 320
μ
S) through register control
Provides up to 2 LEDs and 3 STOP outputs
Every LED pin drives up to 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 to maintain stable voltage when chip is powered on
