INTRODUCTION

SNC208S is a single channel voice synthesizer IC with PWM direct drive circuit. It built-in a 4-bit tiny controller with six I/O pins. By programming through the tiny controller in SNC208S, user’s varied applications including voice section combination, key trigger arrangement, output control, and other logic functions can be easily implemented.
