W523X PowerSpeech LOW VOLTAGE ADPCM VOICE SYNTHESIZER
GENERAL DESCRIPTION
The W523X is a programmable speech synthesis IC that utilizes the ADPCM coding method to generate all types of voice effects. The W523X'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 W523X family includes the W5231, W5232, W5233, and W5234. The ROM size of each of these products is shown below: BODY Second W5231 3 Sec W5232 6 Sec W5233 9 Sec W5234 12 Sec
Note: All of the playback lengths are estimated by typical applications.

Notes: 1. In principle, the playing speed determined by ROSC should correspond to the sampling rate during the coding phase. The playing speed may be adjusted by varying ROSC, however. 2. Rs is an optional current-dividing resistor. If Rs is added, the resistance should be between 470 and 750 . 3. R is used to limit the current on the LED. 4. Cs is optional. 5. The DC current gain 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!
