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.
