W5280 General Description
The W528xxx family are programmable
speech synthesis ICs that utilize the ADPCM coding method to generate all
types of voice effects.
The W528xxx's LOAD and JUMP commands and four
programmable registers provide powerful userprogrammable functions that make
this chip suitable for an extremely wide range of speech IC
applications.

W5280 Features
· Programmable speech synthesizer
· Wide operating voltage range: 2.4 to 5.5 volts
· 4-bit ADPCM synthesis method
· Provides 4 direct trigger inputs that can easily be extended to 8 or 12 matrix trigger inputs
· Two trigger input debounce times (50 mS or 400 mS) can be set
· Provides up to 2 LEDs and 3 STOP outputs
· Every LED pin can drive 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 ensures stable voltage when chip is powered on
· Can be programmed for the following functions:
- 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)
- Four playing modes:
One Shot (OS)
Level Hold (LH)
Single -cycle level hold (S_LH)
Complete-cycle level hold (C_LH)
- Stop output signal setting
- Serial, direct, or random trigger mode setting
· Four frequency options (4/4.8/6/8 KHz) and 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
· Provides the following mask options:
- LED flash type: synchronous/alternate
- LED1 section- controlled: Yes/No
- LED2: section-controlled/STPC-controlled
- LED volume-controlled: No/Yes
