SN66168
4-Channel Speech Controller
„ INTRODUCTION
SN66168 is a 168 seconds single chip 4-channel voice synthesizer IC which
contains I/O ports and a tiny controller. By programming through the tiny
controller, user’s applications including section combination, trigger modes,
output status, high performance melody, multiple voices, and other logic
functions can be implemented.
