LCD Controller with Voice/Dual Tone Melody

INTRODUCTION

SN6A514 is a series of single chip voice/dual tone melody synthesizer IC with

16*64/8*64 LCD direct drive capability which contains two 4-bit I/O ports, two

optional 4-bit output ports and a tiny controller. By programming through the tiny

controller, user’s application including LCD display, section combination, trigger

modes, output status, voice/melody playing and other logic functions and then

be easily implemented.
