DESCRIPTION
The UTC 1812A/1812B/1813 is a CMOS LSI chip designed for
use in sound effect products .It is equipped with tone circuit, noise
circuit and other control logic to generate different sounds
including rifle gun, machine gun, booming sound, door bell, alarm
etc. The customer supplied sound source can be analyzed and
programmed into an internal ROM by changing a mask layer
during device fabrication. The UTC 1812A/1812B/1813 is suitable
for various toy applications.
