SONIX SN67009

SN67009
Speech Controller
„ INTRODUCTION
SN67009 is a 9 seconds single chip voice synthesizer IC which contains I/O
pins and a tiny controller. By programming through the tiny controller, user’s
applications including section combination, trigger modes, output status, and
other logic functions can then be easily implemented.
