One Channel Direct Drive Speech Controller
December 20, 2000
1
INTRODUCTION
SN65020 is a 20 seconds one-channel single chip voice synthesizer IC which
contains a PWM Direct Drive Circuit. There is one 4-bit I/O port and built in a
tiny controller. By programming through the tiny controller, user’s applications
including section combination, trigger modes, output status, and other logic
functions can be easily implemented.
