SN68006
Speech Controller
INTRODUCTION
SN68006 is a 6 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.
