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.
