W581XX
ADPCM VOICE SYNTHESIZER
ENHANCED PowerSpeech
Publication Release Date: July 1998
- 1 - Revision A2
GENERAL DESCRIPTION
The W581XX is a programmable IC speech synthesizer that utilizes the ADPCM coding method to
generate all types of sound effects. The W581XX's LOAD and JUMP commands and eight
programmable registers provide powerful user-programmable functions that make this chip suitable
for an extremely wide range of speech IC applications.
The W581XX family includes the W58101, W58102, W58103, W58104, W58105, W58106, W58110,
W58115 and W58120. The playback lengths for each of these products is shown below:

Notes:
1. In principle, the playing speed determined by ROSC should correspond to the sampling rate during the coding phase.
However, the playing speed may be adjusted by varying ROSC.
2. RS is an optional current-dividing resistor. If RS is added, the resistance should be between 470 and 750 Ω.
3. R is used to limit the current on the LED.
4. CS is optional.
5. The DC current gain β of transistor 8050 ranges from 120 to 200.
6. All unused trigger pins can be left open because of their internal pull-high resistance.
7. No warranty for production.
