1. GENERAL DESCRIPTION
The W528Sxx family is programmable speech synthesis ICs that utilize the ADPCM coding method to
generate all types of voice effects.
The W528Sxx'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.
The W528Sxx family includes 9 kinds of part numbers with the same function except for the voice
duration shown below:

2. 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 (20 to 40 mS or 160 to 320 S) 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:
W528SXX
Publication Release Date: June 13, 2003
- 3 - Revision A2
- 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

6. FUNCTIONAL DESCRIPTION
The W528Sxx family provides up to four direct trigger pins, which can be extended to eight or twelve
matrix trigger inputs, up to three stop signal output pins, an LED section control, and powerful
programmable features. The JUMP and LOAD commands and four programmable registers can be
used to program the desired playing mode, stop output signal form, LED flash type, and trigger pin
interrupt modes.
The chip's programmable features can also be used to develop new, customized functions for a wide
variety of innovative applications.
6.1 Instruction Set Description
This section describes three types of instructions:
Unconditional instructions, which are executed immediately after they are issued.
Conditional instructions, which are executed only when the conditions specified in the instructions
are
satisfied.
END instruction, which is used to stop all device activity.
