One Channel Speech Controller

1. INTRODUCTION

SNC26120 is a one-channel voice synthesizer IC with PWM direct drive circuit. It built

in a 4-bit tiny controller with one 4-bit input port and two 4-bit I/O ports. By

programming through the tiny controller in SNC26120, user’s varied applications

including voice section combination, key trigger arrangement, output control, and

other logic functions can be easily implemented.

2. FEATURES
