W5230 PowerSpeech LOW VOLTAGE ADPCM VOICE SYNTHESIZER
GENERAL DESCRIPTION
The W5230 is a CMOS IC that is used solely for the purpose of demonstrating W523X series Low Voltage PowerSpeech products. The W5230 employs the same JUMP-GO architecture as Winbond's other PowerSpeech products. Unlike standard products, however, the W5230 does not include built-in memory, because the chip is designed to serve only as a demonstration chip for the W523X series ICs. Hence the W5230 must be operated with an external memory device (e.g., an OTP memory). The W5230's LOAD and JUMP commands and four programmable registers provide powerful user-programmable functions that make this chip suitable for a wide range of speech IC applications.
FEATURES
* * * * * * * * *
Wide operating voltage range: 1.2 to 3.6 volts Serves as demo chip for W523X series products (no built-in ROM) Programmable speech synthesizer 4-bit ADPCM synthesis method and 8-bit D/A converter RC oscillator with built-in capacitor; voice output frequency typically at 6 KHz Provides 4 trigger inputs Drives 2 flash LEDs for two batteries 3 STOP output signals Flexible functions programmable through the following: - LD (load), JP (jump) commands - Four registers: R0, EN, STOP, and MODE - Conditional instructions - Speech equation - Global repeat (GR) setting

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 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.
