SNC12120  
One Channel Speech Controller  
1. INTRODUCTION  
SNC12120 is a one-channel voice synthesizer IC with Push-Pull direct drive circuit. It  
built in a 4-bit tiny controller with four 4-bit I/O ports. By programming through the tiny  
controller in SNC12120, user’s varied applications including voice section combination,  
key trigger arrangement, output control, and other logic functions can be easily  
implemented.  
2. FEATURES
