1812A/1812B/1813
SINGLE SOUND GENERATOR
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.
