SNC11A

One Channel Direct Drive Speech Controller

INTRODUCTION

SNC11A 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, two 4-bit I/O ports. By programming

through the tiny controller in SNC11A, user’s varied applications including voice

section combination, key trigger arrangement, output control, and other logic functions

can be easily implemented.
