1. INTRODUCTION
SNC21085 is a one-channel voice synthesizer IC with Push-Pull direct drive circuit. It
built in a 4-bit tiny controller with three 4-bit I/O ports. By programming through the tiny
controller in SNC21085, user’s varied applications including voice section combination,
key trigger arrangement, output control, and other logic functions can be easily
implemented.
