SN67120 Datasheet Speech Controller

Manufacturer: SONiX Technology Company

Overview: SN67120 Speech Controller „ INTRODUCTION SN67120 is a 120 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.
