General Description
The HT2830 is a CMOS LSI chip designed for
use in sound effect products. It is a body struc-
ture including tone circuit, noise circuit, an up-
down counter, and other control logic to
generate various sounds such as J E T plane,
motorcycle, helicopter, train, and so forth. Fea-
tures from the customer’s sound samples can be
analyzed and programmed into an internal
ROM by changing a mask layer during device
fabrication. The HT2830 is suitable for various
toy applications.
