SONIX SN65016

SN65016
One Channel Direct Drive Speech Controller
„ INTRODUCTION
SN65016 is 16 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.
