SNC26300
One Channel Speech Controller
1. INTRODUCTION
SNC26300 is a one-channel voice synthesizer IC with PWM direct drive circuit. It built
in a 4-bit tiny controller with one 4-bit input port and two 4-bit I/O ports. By
programming through the tiny controller in SNC26300, user’s varied applications
including voice section combination, key trigger arrangement, output control, and
other logic functions can be easily implemented.
