SN6A060
LCD Controller with Voice/Dual Tone Melody
INTRODUCTION
SN6A060 is a single chip voice/dual tone melody synthesizer IC with 4*32 LCD direct drive capability which contains two 4-bit I/O ports, one 4-bit output ports and a tiny controller. By programming through the tiny controller, user's applications including LCD display, section combination, trigger modes, output status, voice/melody playing and other logic functions and then be easily implemented.
