SNC5A8

Two Channel Direct Drive Speech Controller

INTRODUCTION

SNC5A8 is a two-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 output ports and three

4-bit I/O ports. By programming through the tiny controller in SNC5A8, user’s varied

applications including voice section combination, key trigger arrangement, output

control, and other logic functions can be easily implemented.
