SNC26041
One Channel Speech Controller
1. INTRODUCTION
SNC26041 is a one-channel voice synthesizer IC with PWM direct drive circuit. It built
in a 4-bit tiny controller with one 4-bit I/O ports. By programming through the tiny
controller in SNC26041, user’s varied applications including voice section
combination, key trigger arrangement, output control, and other logic functions can be
easily implemented.
