SN67061
Speech Controller
 INTRODUCTION
SN67061 is a 61 seconds single chip voice synthesizer IC which contains I/O
pins and a tiny controller. By programming through the tiny controller, userâs
applications including section combination, trigger modes, output status, and
other logic functions can then be easily implemented.
