SN6A513
LCD Controller with Voice/Dual Tone Melody
INTRODUCTION
SN6A513 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.
